The cancel on this pair, though not easy to see in this scan, starts "Elmira, N.Y. Caparulo's S...."
Caparulo's what? I haven't been able to find the answer to that on the internet. Maybe a postal station in some business?
BTW: This is not a color variety of this particular stamp issue. For some reason, my scanner chose not to show its true color.
My thanks in advance for any help.
