Disney-comics digest #315.

TRYG:
	No, Marvel doesn't distribute its own comics on a national basis
(i.e. newsstands, other public places). Local distribution companies
(i.e.: the Mafia) has charge of that. 
	Actually, the system may have been different back in the 50s...
I would be surprised if Dell didn't control its own distribution
somehow, but I think DC was owned by a company that distributed
periodicals, and that was the reason why, in 1956, Marvel/Atlas was
forced to cut back from publishing about 100 titles to about 6 --
because they were limited to that many by their competitor.
