I'm going to have to disagree with the idea that all the mossy cork/swirls were pre-cork. I think mossy cork/swirls continued to be made for awhile.
Corks were around by early 1930, whereas Carnelians were advertised as "new" in Jan. 1934. How long would Akro have been calling them "new"?
Paul, are you thinking of Cardinals? They were made before corks were first made, and had a definite pre-cork and cork version. Or Imperials? Those had a pre-cork version and the box stayed in use with other marble types.
Final edit (and fwiw): The mossy swirls were still being advertised in Sept. 1936. The popeye boxes had them in it in the ads. I've got mossy swirls in ads for 1934, 1935 and 1936. That's a long time to have them hanging around as old stock. At least I can't help thinking so.
