I made a presentation at last year's 52 Plus Joker convention about Bicycle Playing Card rarities and oddities. My presentation ended with a description of the Autobike #2 back. It is known as Back #9 because Mrs. Ruth Robinson numbered it as such in her guide to Bicycle Playing Cards published in 1955. In more than 20 years of collecting Bicycle playing cards I have never seen a deck, single, or even an image of this card design other than the poor quality one in Mrs. Robinson's book. It doesn't show up in advertising materials, salesman's sample books, and no other serious Bicycle card collector I know has ever seen it.
Chas0039 is right: Target is selling a deck that is actually a reprint of Autobike #3 (back #10 in Mrs. Robinson's book). While unquestionably rare, Autobike #3 definitely existed prior to the Target release as I have one full red deck and several singles in red and blue. Interestingly, my deck is a UK issue in a cardboard sleeve box.
Arguably, Autobike #3 is a more attractive back anyway as it has the winged wheel in the center, but I think it's funny that even after finally attempting to release the elusive Autobike #2, it still doesn't exist!
P.S. The images of Bicycle cards on Jim Knapp's site are almost entirely from my website:
