Ok.
Here are my 2 cents.
I don't think there is anything wrong with a classification system for pictures. As Lance stated above very well, I think a system allows people to have more conformity when discussing what types of pictures they have.
I think it is akin to the classification system used for baseball cards (R,F,E,T,M,W, etc). Why would this be bad? It allows people to have some basis to judge pictures for historical significance, rarity and value, among other things.
Now if you want to argue as to the exact definitions of what makes a specific type of photo, I don't disagree. I do think 2 years to be considered original is a bit restrictive. On other hand not everyone agreed with Burdick when he started to classify cards. Heck, not everyone agrees with some of his choices to this day, but his main framework still exists and I think helps collectors.
In general, I am not a fan of Third Party Authenticators, be it for cards, autographs, or pictures. As such, the only time I would grade or authenticate an item, is if I felt it would significantly help the sale price.
I have bought a few things previously from Henry and found him a good guy to deal with. The true measure of a dealer is how they handle this type of problem, when it comes to light.
Now back to scouring ebay!
