The most likely answer is a bag with an “A” monogram or alphabet design —for example, an “A” tote or alphabet bag. One clear match is an Alphabet letter bag A that is printed with the letter A on both sides.

Likely matches

  • Alphabet/A tote bag : a tote printed with a large letter A.
  • Letter A canvas tote : a pre-monogrammed canvas bag with A on it.
  • Bag charm shaped like A : a charm, not the whole bag, but sometimes mistaken for the bag’s logo or detail.

Best guess

If you saw just a plain bag with a single A, it was probably an initial bag or monogrammed tote rather than a specific luxury brand.

Note

A Reddit post also suggests that an A-shaped charm on a bag may belong to Aspinal of London , but that refers to the charm shape, not necessarily a bag with a printed A.

Would you like me to narrow it down by style, color, or where you saw it?
