Thanks to those collectors who responded to my earlier post on the "Silver Slipper Left" match. Since several mentioned covers other than the "red series", here are all 21 that I have from this club. I believe I've given enough info in the pic to see the differences in the fronts of these. There are also differences on the inside printing on some. It's interesting that, unlike some of the other casinos Howard Hughes owned, none of these covers mention his name.

I'd be interested in any dupes you might have not shown here.

I have dupes of some of those shown and will look for them if anyone needs a specific one.

This is a big scan; you'll have to scroll L-R to see all 21 matches.
