Yeah, it does look better. So I would do more research to find out.
By chance is there any 3 digit small number on the bottom edges or the back?
Sometimes, advertising will have a 3 digit number or even a letter and then 3 digits to signify the date it was made.
For an example, I have 2 original 1948 GMC Truck brochures with this: "A-348" on the corner of the rear. The 48 stands for the year they were printed. Usually the last 2 digits are the year. (if there are numbers like that). Reproductions usually will not have them....unless someone is trying to pull a fast one
