scott brockelmanafter rereading the thread i would like to address a couple of issues, first on the gehrig card, that appears to be nothing more than a rubber stamp "forward" stamp commonly used by the post office, probably vintage but not a redemption stamp by any means.
also, AGAIN without close examination they overprints are all TOO smiliar! COULD THEY BE MACHINE OVERPRINTS, the rotary press method was common of the time, which may explain why the long stamp was not perfectly aligned and blurred?
also many of the overprints have purple ink residue on the front, so they were definetly stacked atop each other, whether single cards or sheets.
the truth is out there
