Rick Rose began selling his first 24 card set in the year 2003 on a individual basis on premium acid free card stock. They were a standard 2.5 x 3.5 card size.
Before 2003, series 1 was first made available on the ebay network or directly from Rose. The printing came from his home on a first come first served basis.
Series 2 and later series followed.
The images of the cards were seen for a time on the davesfunstuff.com network before the Series 1 sticker set began being made available for purchase.
