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).
Thanks for sharing. Richard Maxwell, who does a lot with kids and marbles in the Kansas City area, visited Wildwood this year for the tournament and posted a lot of pictures in some of the Facebook marble groups (or on his own FB page).
