Here's a picture of the building, the one that looks like a Jennings slot machine . I don't know if it was the Golden Slot Club when the picture was taken. (Brian's scan of this postcard is on page 41 of CCTN Vol. 19 #4 is clearer than my photo).

If you drag out your CCTN vol. 19 #4, there's a picture on page 40 of the Fortune Club...same building, better view of the front. (Same photo can be found at nevadacasinoashtrays.org on the Buckley's page)

That feature matchbook is one of my favorites, too!
