This is the only d310 or d311 I've ever seen with an Overprint on the back. This looks very crisp and clear, so I don't feel this is a typical back stamp at all. It reminds me of the e94 overprints in their clarity and quality of the stamp. I included a small pic of an e94 overprint so you can see what I'm referring to.
The overprint reads -
Text of the overprint (some obscured) reads, "MEET THE CHAMPIONS at the ANNUAL BALL given by the BALL PLAYERS, COTILLION HALL 159 Church St., SATURDAY EVG, NOV. 25. A valuable 26 Piece Silver Set will be Drawn for by All Ladies Present. Music by Gormah & Levy Dancing All Night.
Very cool oddity and very unique, possibly unique for the entire set.
Asking $220 delivered!
