Hi, Stampcrow... firstly, it's a cancel,
not a mint stamp, so - what the back looks
like isn't very significant comparatively
to an unused copy...
Second... seller states the following...
"Norman C. Hinds, Jr. APS # 083032, a dealer member since 1975. Member of Florida Stamp Dealers' Association, USPCS, GPS, GCCG"
Lastly, you have
ebay Buyer Protection,
which I highly doubt you would need...
I don't collect cancels, otherwise we
wouldn't be having this conversation...
I would have already purchased it, all
based upon the above...
My advice to you is that if you can
afford the $22, you should buy this
stamp... I highly doubt you would ever
see another in this condition, not to
mention the low price... your choice...
