Just picked one of these up at a local "antique" store...any idea what it's worth? It's 3.5 inches across, kinda square, red lettering that says: North end of Lake Tahoe, the friendliest casino in Nevada, in the heart of Reno. And there's a little guy (shaped like Nevada!) right in the middle, wearing a hat. I'm willing to part with it if anyone neeeeds it. I'll scan it if you want to see it, but it looks like it's in pretty good shape. The price tag left a small square of dried paste on the back, but I figure a real ashtray collector would know how to get it off of there better than me. Book value would be helpful--I have a feeling I paid too much for it tho...email me if you're interested. Thanks!
