Photos Question - Type 1, Type 2, Type 3, etc.

[Lucas00]

This is absolutely a type 1.

Wire photos
Are very easy to identify as they usually always have an article on the front describing the photo. They weren't really implemented until the mid 30s by the associated press for sporting use. They also are significantly lesser quality than a news/press photo. If this was a wirephoto I would expect it to be about half the quality of yours.

Good article.

You have a "News" or "Press" photo. With an original period news clipping and original pencil dating. Which are almost always sure fire signs of a type 1. These are second only to original photographer shots in terms of desirability.

Type 2s are pretty easy to identify as well. They will generally be very high quality with a single stamp or two or maybe a newspaper clipping that is out of the range for a type 1 date to make sense, (say a babe Ruth photo in uniform used for a 1950s article).
But they can be tricky. And sometimes it's frankly impossible to tell them apart from a type 1. Maybe George Brace waited 3 years after taking a photo to get it developed. Would anybody know the difference? No.

Once you go beyond type 2 it gets more and more obvious. Cream white borders. Bright white backs. Image quality that is severely lacking. No stamps at all. I would 99% of the time stay away from these.
