Here's something I've never seen before: a "rack pack" of DARK SHADOWS trading cards from 1968.
Sealed "wax packs" from this series pop up online from time to time, but this is the first I've heard that these cards were ever issued in the dreaded "rack pack" format. Rack packs were often surplus cards re-packaged in bulk as a way for companies to clean house, so to speak (though I admit the market might have been very different in 1968 than when I started collecting cards many years later).
One of these packs is now available for auction on Ebay. It ends shortly after midnight and has a starting bid of $125. I don't know how reasonable that price is, but this is a pretty rare item regardless.
