Hi, Gator... no cert... I may or may
not send it in for one... I have not
really decided, as there's more visual
evidence that it is what it appears to
be, versus a possible fake...
If genuine, given the 1915 date, it
quite obviously cannot be anything but
461, given the 499 did not exist at that
time, not to mention that if it (was) a
fake, it very likely would still be in
somebody's collection, and would not
have been floating around on
ebay by a
cover seller for sale at the lowly price
of $1.62 (+ $1.00 shipping), which is
what I paid for it, or offered on
ebayat some 'pie in the sky' (Langs-Type)
offering price...

Wt1... thank you for the link...
I'll definitely read it...
