>Did this guy scan flyers just to make teaser thumbnails?
I am guessing the site owner's thought of: "...maybe none of the visitors care about seeing a larger size view of the flyer, but just want to read the text on the web page."
iirc The specific Taito flyers from the Taito company (Japan region) came from their company web site many years earlier when TAFA had just started in 2000.
The scans were too small and Dan H. came to the rescue and uploaded larger size scans of some of those same flyers. Several previous flyer scans were replaced by Dan's upgraded flyer scans. I hope he continues in the future and finds more flyers and uploads them to TAFA. I am guessing Dan is on a break at this time.
