Unknown
Unidentifiable Graffiti or Tagging Artist · Street Art / Graffiti
None identified
Era
Modern Era (post-2010)
Item Type
Window / Glass Pane
Condition
Poor - the signature is on a public surface susceptible to cleaning, weathering, and scratches; the item itself is part of a structural environment.
Rarity
Common / Non-collectible
Overall Assessment
This is not a traditional celebrity or sports autograph. It is a piece of graffiti or a personal tag on a window with no commercial or historical value in the memorabilia market.
Authenticity Assessment
Unverifiable - Likely non-famous street tagging or personal marking. Confidence: Near Zero.
Signature Style
Stylized 'tag' style featuring the characters 'AC', a symbol resembling a cross or 'H', and the number '13'.
Signature Characteristics
Angular 'A' with a single-stroke 'C' loop; '+' symbol followed by '13'. Constant pressure suggests a felt-tip marker. No professional flourishes.
Ink & Medium
Blue liquid-ink marker, possibly a broad-tip felt marker or glass-grade ink on a non-porous glass or acrylic surface.
Item Description
A signature or tag written on a transparent pane of glass, likely a storefront window or display case in an urban environment.
Estimated Value
$0.00 USD
Comparison to Known Examples
Does not match any high-profile athletes or celebrities. The '13' is a common numeric suffix in gang-related or neighborhood-specific tagging.
Authentication Tips
Compare character strokes to local graffiti databases or street art directories; look for fluid one-motion strokes consistent with tagging.
Certification Recommendation
None - professional services like PSA or JSA do not authenticate unidentified street tags or markings on building structures.
Red Flags
The location (a window) and the style (tagging) are indicative of vandalism rather than a collectible autograph.
Provenance Notes
None exists. This appears to be a spontaneous marking in a public space.
Historical Context
None. Likely represents a modern transient marking in a city or university setting.
Market Trends
There is no secondary market for unidentified glass-written tags.
Investment Potential
None.
Similar Autographs
Local graffiti 'handstyles' or gang-related identifiers.
Display & Preservation
Not applicable as the item is a fixed pane of glass. Documentation via photograph is the only form of preservation.
Interesting Facts
The number 13 is often associated with specific affiliations in certain regions (e.g., California or the Southwestern US) when used in tagging.
