Type 1 photo dating

I wish Henry Yee would release a second edition. The current type system is of value. However, it can be confusing. I will use these two Aaron photos as an example. The first was taken in 1954 during Aaron’s first Spring Training. In 1958 United Press and International News merged. The stamp on the back of this photo most closely resembles the 1958-early 1970s UPI example (no zip) on page 168 of Henry’s book. However, that stamp has a border. The stamp on this photo is sans border. In pencil above the stamp is written INP 1249903 1954- Charlie Grimm & Hank Aaron Milwaukee Braves. Henry’s book states “Some previously unstamped photos from earlier periods were stamped in 1958 or shortly thereafter”. Is this such a photo? If you date the photo by the stamp it would be considered a Type II. If you judge it by the hand written notation and International News seven digit number it would be a Type I. Obviously there is quite a difference in value between these two designations.
The second photo was taken in 1957. However, per Henry’s book (page 175) the Wide World Photo stamp on the reverse was used Mid 1940s – 1954.
