Evidence

POSITIVE
  • —
NEGATIVE
  • photo 1: clearly visible red Unionbay fabric label; seller identifies the brand as Unionbay.
  • photo 1: floral textile exterior, faux-leather trim, decorative buckle, and non-Coach design language are inconsistent with a classic vintage Coach leather handbag.
  • photo 2: visible Unionbay label inside the bag and light synthetic-looking lining; no Coach creed or wordmark is visible.
  • photo 3: floral canvas/textile construction and adjustable strap are unlike the usual unlined glove-tanned leather construction of vintage Coach classics.
MISSING INFORMATION
  • photo 1: bottom, corner, and hardware close-ups are not provided.
  • photo 2: the full interior and any care/manufacturer tag are not shown, although the Unionbay label is visible.
AUTHENTICITY CONCERNS
  • ⚠ photo 1: the visible Unionbay label identifies another brand, so this is a non-Coach lookalike/alternative-brand bag rather than a misidentified Coach item.
  • ⚠ photo 1 and photo 2: no Coach identifiers are visible.
