Hi Susan. Do you know if this is a lithograph?

Yes, it is a lithograph or a similar printing process. It's a variant of the original albumen photograph ML-O9, taken by Brady in 1861. Quite a bit of retouching was performed on this copy, which was also not uncommon in the president's idealized images.
