Don,
That is ALMOST the same design...but the sketch of the building on mine dates earlier than yours. The rest of the design is the same, but my cocktail waitress doesn't have any yellow, and mine is yellow & black-yours looks purple & yellow. It probably is authentic, but the seller contacted me a couple of times having "just found a few more" each time. I couldn't help but wonder...maybe the seller was just "hoarding"!
