I am listing a few duplicate marbles books and some magazines with marble related covers or articles this evening on eBay. Might be something that you are looking for. Will also be listing some marbles soon, probably over the weekend. Thanks for looking.

Top pic looks like cat's-eyes - hard to tell which maker from one view. 2nd pic from bottom, left one (green w-yellow stripes) fits in the Imperial packaged type (made in Far East) - newer.
Here's "flyer" info for the show. I know a few people from the Seattle (Tukwila) Show that just ended today mentioned that they were goiing to the Las Vegas Show.
First two looks like swirls - hard to tell who made. Middle looks like Master; to the right of it is Peltier Rainbo and last one on right is Marble King Patch & Ribbon.
In going through some marble advertising material, I came across this 1958 VFW Marble Tournament Rules Booklet. Advertising Billy the Kid jeans also (must have been a sponsor).
