You know, scanning full pages at 1600dpi is VERY time-consuming...

Rather than kill everyone's bandwidth here, I've created a standalone web page showing the R15c double transfer pages I purchased at COMPEX. The page uses lower-resolution images, but clicking on each image will load a 1600dpi image. Be forewarned, the full-page images at 1600dpi are approximately 50MB each.
While I had only made a peripheral scan of the pages before deciding to buy (took all of about 20 seconds), upon closer examination there's far more here than I initially thought. It's not just minor DTs, but some pretty dramatic double transfers, including ones I haven't seen before... in quantity.
I don't think I've ever seen this many DTs in one place before.
