Now that is a collectors man cave. Very nice. Looks like it took a lot of years to get that sort of collection. Is that a really long air hockey table?
That is a 1940's full size shuffelboard. It is a game where you slide pucks into marked areas that have point values. Each player or team has 4 pucks. You can knock your opponets pucks off to remove their points. You can play to 15 or 21 points. That is a very basic explanation of the game.
I've been collecting stuff since I was a kid, I go to quite a few auctions, garage sales and of course flea markets.
