Apparently the lithographs were part of an annual series depicting Hall of Fame Baseball players interacting with children, which were published by the advertising firm Brown & Bigelow from 1950 until 1972. http://www.baberuthleague.org/images/March2005web.pdf
The Connie Mack version was printed by the Philadelphia Athletics with a home schedule on the back in color '54 and '53 and in black-and-white in '52. I also have one with an '52 Indians schedule on the back sponsored by K.D. Hiller for Sheriff of Tuscarawas County.
The John McGraw lithograph appears on a '53 Athletics/Phillies combo sponsored by I.C.C. Loan Company and a '54 Cardinals sked sponsored by the Pacific Cafe.
The Pacific Cafe did another 1954 Cards' schedule, this one with the Ty Cobb lithograph. This one misspelled the restaurant's name as "Pacifac Cafe"--perhaps the printer did the McGraw for them after that for free. I also have a 1955 Phillies' schedule with the Ty Cobb lithograph sponsored by Hawk's Cities Service, and on Ebay I saw the Ty Cobb artwork on a 1954 Orioles Schedule sponsored by Jensen Needles.
Here's an image of the Honus Wagner lithograph: http://www.antiquesnart.com/HWagnerCF.jpg
The artist of the Wagner lithograph was Bill Medcalf, who worked for Brown & Bigelow and was primarily known for his depictions of scantily clad women. It appears on several MLB schedules in my collection, including a '55 Reds' sked sponsored by Rueter's Sunoco Service
