Here's a different perspective from a younger collector. One of these 20/30-something collectors. I don't think it's ever going to drop off like a lot of guys keep saying. I've only been collecting for a few years now comparatively and I've seen people go from looking at some of the guides 10 years ago and getting a good laugh, now a lot of us are lucky to pay those same prices. The fact that this stuff is eternally tied to both hot rod/classic car culture and Americana nostalgia gives it a solid footing for the future as far as I can tell. Now some items are dropping off, I've noticed a lot of us that don't have the luxury of doubles and triples to compare with are avoiding the reproduced signs entirely. Another portion of the young guys have never gotten a chance to even see half of what's out there! And if we can't see we'll never stay up at night thinking about it or cash out our savings to buy it. So we stick with the stuff we know and already covet. Just one guys perspective. A lot of the younger guys don't have the first hand knowledge of this stuff, but heck, last time I checked most of us have never used a curb pump! We all find our own connection to it and we'll go looking for the guys that have it. The fact is a lot of our collections have been through several hands and I can only hope they'll go through several more.
