Ad type was made for making mailable material like advertising and greeting cards. It is coated without a baryta layer so that it can be folded without cracking. I don't know what sort of sizing was used in place of the baryta. The emulsion was similar to Azo and came in 6 contrast grades.A indicates the Ad Type surface and 1 is the contrast grade. --- Richard Knoppow
