Looking back on it, it might have been a good idea to sign my name - if anyone is wondering, this is the card I sent:

Except not a horrible scan of a quickie contact sheet.

I've been out of town, but today sorting through the mail i found cards from drpsilver and polyglot (i think). One a nice 4x5 contact print from Delta 100, the other a 5x7 from some 35mm Pan-F. Unfortunately the 5x7 got a little beat up in the mail and has sort of a crease in it, but it still looks great.
