davidcyclebackBuy based on the material's collectible merits rather than price tag. You'll find lots of cool stuff that doesn't register on the Memorabilia Market Exchange. For example, I always though vintage booklets enticing. They're much like baseball cards, but a whole lot cheaper and often much rarer.
I once had a simple 19th century regional Michigan baseball league schedule booklet that baseball card collectors paid little attention to. Then the Ford Museum asked to purchase it for their museum, where the booklet currently resides. That confirmed my suspicions that booklets can be cool, even if they are part of the in crowd with baseball card collectors.
