Andy Warhol Signatures: When a Forgery Combines Multiple Periods
At first glance, from an expert perspective, the signatures presented in this case raise immediate doubts. However, this is not the central point of this study.
Rather than focusing on the conclusion itself, this case provides an opportunity to examine a relatively clear example of a broader phenomenon: the accumulation of multiple characteristics drawn from different authentic models, combined without coherence.
While more complex cases exist — where such constructions are more subtle and difficult to detect — this example allows for a clearer understanding of the underlying mechanism.
For this reason, we have chosen to present this case as a simplified illustration of how certain forgeries are built, and why the presence of multiple “correct” elements does not necessarily indicate authenticity.
Two Forged Signatures Attributed to Andy Warhol Showing Identical Structural Patterns
Two Objects, One Hand
The case involves two separate items, each bearing a signature attributed to Warhol.
A comparative analysis quickly reveals that both signatures share highly similar structural features, suggesting that they were produced by the same hand. This is a critical observation, as it allows us to move beyond isolated examination and consider the broader pattern.
However, similarity alone does not imply authenticity.
In this instance, what becomes striking is not just the resemblance between the two signatures, but the way in which they appear constructed.
A Combination of Periods
As previously explored in one of our articles on signature evolution, handwriting — and particularly signatures — can change significantly over time:

Warhol’s signatures are a well-known example of this phenomenon. Throughout his career, his signature evolved significantly:
-
sometimes composed of first and last name separately
-
sometimes reduced to initials
-
sometimes executed in a single continuous movement
Each period retains its own internal logic and recurring features.
What makes this case unusual is that the signatures appear to combine elements from different periods — but without consistency.
For example:
-
the first part of the signature reflects a structure associated with one phase
-
the second part attempts to imitate characteristics from another
Rather than forming a coherent whole, these elements seem artificially assembled.
We can see here that the forged signature is a blend of two original signatures made by Warhol at different times:
The Illusion of Variation
A common argument encountered in authentication requests is that unusual signatures may simply result from difficult signing conditions.
As explained in our article on how signing conditions can influence a signature, external factors such as speed, environment, or physical condition can indeed affect the appearance of handwriting:

Indeed, external factors such as speed, environment, or physical condition can influence the appearance of a signature.
However, from an expert perspective, such variations remain within a certain framework.
Even under less favorable conditions, the fundamental movements and structural habits of a writer tend to persist.
These core elements — sometimes referred to as the “DNA” of a signature — are deeply ingrained and do not disappear entirely.
In this case, the issue is not variation, but contradiction.
Certain features appear not only inconsistent, but reversed or misinterpreted, which cannot easily be explained by natural variation alone.
When a Signature Becomes Overconstructed
Another notable aspect of this case is the overall impression of the signatures.
Rather than displaying the fluidity and spontaneity typically observed in authentic examples, the line appears controlled and hesitant.
This often results in what can be described as an “overconstructed” signature — one where multiple recognizable elements are deliberately combined in an attempt to reinforce credibility.
Paradoxically, this approach tends to produce the opposite effect.
By trying to include too many characteristics at once, the forger introduces inconsistencies that would not normally coexist in a genuine signature.
Final Assessment
While each individual element might appear plausible in isolation, their combination creates a lack of coherence that is difficult to reconcile with authentic writing habits.
The presence of repeated structural inconsistencies across two separate items further supports the conclusion that both signatures originate from the same non-authentic source.
This case demonstrates that the evaluation of a signature must go beyond surface resemblance and consider the internal logic of its construction.
Why This Case Matters
This case highlights a subtle but important form of forgery: one that does not rely on crude imitation, but on the selective combination of authentic features.
For collectors, such cases can be particularly misleading, as they may appear convincing at first glance.
In situations like this, obtaining a professional assessment can provide clarity and help avoid misinterpretation. A first expert opinion allows for an initial evaluation based on structural analysis and comparative methodology, offering valuable insight before any further steps are taken.
