This is an excellent bargain from a wonderful seller. This is a rare invitation with excellent graphics that should find a good home in any collection. There is no marking to indicate which firm produced it. I feel it was made by a regional firm with somewhat limited distribution. It is priced at an eminently reasonable $46 as a BIN. (If I didn't have one already, it would be already gone!) Someone needs to scoop this up pronto!
07/18 Update: I'm glad to note that someone followed my advice and bought this fine invitation a scant 19 minutes after my post.
