OK went through the whole Butcher Collection quickly yesterday, just men in shirts with out vests or overcoats. (That messes up another myth.) Sorted today, 15 back button, 15 banded collar frond button and 39 fold down with some of the banded/back button pictures having fold down in them also.
Kinda blows the popular idea I've heard but not believed for years. Will do some cropping and fade removal as I have time.
To save making a big cluster mess I'll just start a new thread for the different types and we can add as we get other pictures from other sources.
