1917 NY Giants Lithograph information
 

I recently purchased a framed 1917 New York Giants Panoramic View Print. Its never been out of the frame and I have no intentions of removing from the frame. The nails in the back are all old square nails and the frame is period correct. I am an antique dealer and its as right as rain. I am wondering if its a variation of the Atwell & Burke Panoramic Supplements. The thing is my print measures longer than others that I have seen when googling. The inside / print area measures approx 14-5/8" x 35-5/8" which is longer than the largest supplement . I am puzzled by this and would appreciate any input.

The m113 uses the same picture, but is smaller, with a hand written Burke Atwell credit in (not on) the bottom right corner of the picture.

I don't remember seeing anything quite that big. Neat looking supplement. Hard to put a value on it.

There is a White Sox version too:

These two teams faced off in the 1917 World Series so I would guess they were issued for that.

The White Sox version also has an m113 version, and both were released in December 1917. They were the last of the m113 posters, with the previous ones having been released two years earlier in December 1915.

Starting in December 1916 everything was an m114, except those two.

I differentiate m113s from m114s by their size, not their release date, because I'm of the opinion that it makes sense to do it that way.
