Dating Buttons by Materials: from Just Buttons magazine 1949
Also with the dating list this was written
"Since this is a brief outline I cannot possibly go into details on each materials. Dates given may not cover the earliest buttons known of that material, but rather will emphasize the dates when that material was most popularly in use-thus covering those an average collector would own. I trust that following table may help the novice date buttons by materials to his own satisfaction."
