I enjoy collecting double transfers, and I stumbled across one tonight that I'm not sure how to attribute. Scott lists several transfers for R15c:
Double Transfer (T15) $65.00
Double Transfer (T15a) $50.00
Double Transfer $12.00
Triple Transfer $40.00
I'm a little confused as to Scott's listing. Is the $12.00 for a specific double transfer, or just any double transfer that is not T15 or T15a?
I hope the board software will scale this image down for everyone and not blow up anyone's screen, as it is a 2400 dpi scan. You'll want to open the image and view it at full size. Look specifically at the bottom scroll, at the lettering for "U.S. Inter. Rev."

EDIT: Nuts. It looks like this message board only scales down images in Firefox. It doesn't work in Internet Exploder and made the page a zillion miles wide, so I've replaced the image with a link to the image. Boy do I hate MSIE.
