There are actually two designs of backs that the club Reno brand used. The one you show is called U.S. Regulation, Arrco re-used backs under different brands also. Do a google on Arrco Club Reno or Arrco U.S. Regulation and you should find something. Arrco has been part of USPC since 1987 and they still make the U.S. Regulation cards.

Hope this helps.
