Marvel in the old days had an advantage over the Marvel of today in that there was newsstand distribution. I have no way of knowing how many outlets there were during the '60s, but I bet there were many more places to buy comics then than there are now, another reason that comics sold more. Of course, comics probably sold a lot more, but Marvel, DC, and the other comics companies were getting ripped off by racketeering national and local distributors, one reason why sales figures from that time period are not entirely trustworthy. As for Stan, he would rib the competition, but it was all in fun. With Bill Jemas, it may be all in fun, but it is hard to know for sure.
