Comics that comply with the code can be offered "sales license". However, the code did not succeed, and publishers of small size ignored it. Some publishers, such as dell comics, have simply refused to join the group. Others, such as the founding member, education comics, also terminated their partnership with them. Some of the remaining members, without a formal review, use the magazine publishers association's sales license directly. In 1950, executive director schultz described it as "the only thing I can say to this association is that it's gone bankrupt, and it's a dead end." However, over the next few years, comics continued to use the magazine publishers association's sales license. Yes, we all aren't designers but we've got our aesthetics, don't we?
