All my Maud Humphrey Bogart larger pieces, say her name on bottom, with a #, etc.

However, I have a mini of one of Maud Humphrey Bogart’s retired pieces, that does not have her name, but has the #915890 Magic Kitten, 1992 HGL, Thailand.
Is this authentic?

Do her mini pieces have her name on them? Piece I have is approx. 2 ” tall. Identical to larger one, except she is holding cat with thread , where large one, ribbon is used.

Thanks in advance.
