The two George Wright pieces are etchings - the black lines were carved into copper, and then printed on paper. They were then probably hand painted.
"show your etchings" is a very old joke.
Amidox was in reference to the name on the shirt collar. If you want to remove it, or if you see similar in the future it might be worth the effort. It doesn't do as well on old stains, and it depends on how much work you want to put into flipping. In my area, a lot of thrifts have marks from Last Call and Off Fifth on the tags - Amodex is really useful for that.
Very cool, thank you for the info. Now that I look at them closely, it does look like watercolor.
