Nice prop, did you do the backside as well?
I agree with the previous post, the signature would read Henry Jones, Jr. But the fonts of CITY OF NEW YORK are fine, and I'm assuming it's replicated from the vintage document, only yours says New York instead of Indiana. As just a thought, you might want to find a nice line drawing of buildings to have on each of the upper corners in place of the more "framland" style scenes depicted there.
Good work!
