1921 !!!
even though the image below is not 100%.... Id have to say this set is no earlier than 1921 and maybe later (Firpo facts) (Bancrofts 1st game with Giants was mid1920) and it would usually be the following year (minimum) before someone who put him in a set of cards this crude
(notice unique shadows on left and right side arm pit... 99.9% proof IMO)
(card images are not square because the original kit image was taken with a camera at an angle, so disregard the slope of the shoulders not matching perfect)
here is the Cobb images, it doesnt help much like I though it might, the uniform with the block "D" and black collar is from 1915-1916 so its an older photo than I was thinking
