Okay, I just saw your ad after a few rotations. How about including your name in the ad? I know you are trying to be modest, neutral, and scientific, but I suspect some people might see "Photographic Emulsion Making, Coating and Testing" and say "Oh, that sounds really interesting, but I think I'll wait for Ron's book to come out."
Ok, well, IDK how to put this, so here goes!
Sean designed the ad! And, there is only so much that can go in that thumbnail, so I guess he was not wrong.
