tonymacg, are these receipt stamps common? The internet (including
ebay) doesn't yield any information about - or further examples of - these stamps.
As for the second stamp, I also wondered if the script was Japanese. When I first glanced at it, I actually thought it was one of the Chinese liberation areas stamps, a few of which look quite similar to this one. I was surprised when I saw it was a Japanese stamp.
I've located a few used examples on
ebay but all the ones I've found so far have regular cds.
