RobSeems like I remember reading about some very good reproduction OJ's done in the past. Perhaps there's someone with more info on that.
Don't know how you could tell if the cards are real under glass, even with a good scan. Heck, one could get those pictures from the library of Congress site, photshop the pictures and print up on appropriate glossy paper with a laser printer, and paste on 120 year old cardboard. That'd be a rather cool looking display of OJ's which could fool even an experienced OJ collector at 1st glance. A bit more sophisticated that the run of the mill fakes, but quite doable.
As for the King Kelly lithograph, it's well known there were some very nice color large reproductions done in the early 1990's, worth $25-50 a piece.
