I am curious if anyone can tell me about the following item: I have Dai Vernon's Stars of Magic tricks, but the format is one I haven't seen apart from these. The tricks are printed on glossy photo paper about 4x6". I don't know if they were published this way or if someone just made them on their own. I have had them a few years, and the apparent age of the pages leads me to believe they are older, but I don't know this for sure. Any info would be much appreciated! Thanks
