Another nifty thing I bought at SoonerCon was, according to the sticker on the back, a "DC Comics Super Hero Superman Stamp Art-WILL HA".
The top part is a bit 9x12 repro of one of the Superman stamps, with art drawn by a young Curt Swan.
The lower part of the thing is a first-date-issued envelope and canceled stamp.
The only way it could be better is if the canceled stamp were of Kal or Kara!
Anyway, the best part was, it was "cover price"! That is, I bought this from a USPS booth in the Exhibitor's Hall at SoonerCon, at "list price," that is $19.99. And not even any sales tax! Spiffy, huh?
By the way, a month or so ago I set aside a bunch of stuff to scan and/or comment about here on the ol' Super Blog. As soon as I can once again FIND THE STUFF, we'll have a lot more posts to share.
