T206 Claude Ritchey and the "doves"
My experience with observing several cards of Ritchey with these backs......
Piedmont 150
Sovereign 150
Sweet Cap 150
HINDU
EPDG
....is that the doves are not visible in the pale blue sky.
Although, under magnification, some of these cards have a very faint hint of
the doves.
The cards of Ritchey with......
PIEDMONT 350
Sweet Cap 350
Old Mill
....clearly show the doves.
I attribute this phenomena to a better quality of Blue (and other) ink(s) used
in the printing of 350 Series cards in 1910.
