Looking for some info on this 1926 Cardinals team photo

Hoping to leverage some expertise from this site. You guys are always so helpful. My mother-in-law brought over what appears to be a postcard from 1926/27? of the Cardinals. Do you guys know if this is authentic and any background info on it? worth?


Thanks in advance!

Looks legit. NM condition i would say $125-$150 value. I think your card would be $25-$50 range??
But, the lines on the card are kind of odd - it almost looks like this is a "proof card" - just not sure.

They have it booking at 4 to 500$ in nrmt - but I think that's high - perhaps.
The one posted appears to be cropped with something? A knife or shape instrument?
