As was mentioned previously, Jay's used the same photo for multiple years. I've attached an example using Mantle. Starting from in the upper left corner, these photos are from the following sets (at least as far as I can tell):

Jay's 1957 Yankee Picture Portfolio with 25
Jay's 1958 Yankee Picture Pack with 12
Jay's 1958 Yankee World Series Picture Pack with 12
Jay's 1958 Yankee World Series Picture Pack with Braves with 24
Jay's 1959 All-Stars
Jay's 1959 Yankee Picture Pack with 12
Jay's 1960 All-Stars
Jay's 1960 Yankee Picture Pack with 12
Jay's unkown year Yankee Picture Pack with 12

There are at least 4 different croppings of the photo. So if you have a single photo it would be nearly impossible to tell what set it came from. And as shown with the last photo, even if you have the complete set, you can never be sure if it is an original set. The bottom right photo appears to be similar to the photos used in the 1958 World Series sets. However, it came with a complete Yankees set which I haven't been able to put a date on.
