1859 Atlantics Print - Origin?
 

Gentlemen.....anyone have a thought about what book this print may have come from? Thank you. Jim

I don't know the answer to your question, but this "1859" image is posed remarkably similar to the 1865 version of the team. Both images appear to have the same team members, with the two end players switching seats. We'd have to do a little research to see if the 1859 Atlantics had the same players as the 1859 team. If not, the dating of one or both of the pictures is wrong.

Jim, could you post the size, if possible? That would eliminate a few possible books.

This image shows the 1865 team. Besides the CdV size pose housed at the Library of Congress, there is a salt print mammoth plate photo of the team, and this image is a copy of that pose.

Corey- This must be same photo shoot, slightly different pose.

I agree.

The print measures 6.75" X 9.75"

Jim, the size should help, that would make the the cover about 7 x 10.
Although the border looks somewhat familiar, I believe those are staple marks which makes it likely it was a magazine, not a bound book.
