Blue Marlin's caps don't claim to be full-fledged reproductions. They have adjustable backs and the name of the team, along with the year, embroidered on the back. They're made of cotton.

Companies pay for rights to most of the images.
The Kansas City Monarch's emblem, for instance, is now owned by the Negro Leagues Base-ball Museum, in Kansas City, Missouri. Royalties run between three and 10 percent. More retro logos will soon appear. The NFL is working with Cohen on a line from the pre Super Bowl American Football League. The Giants are bringing back their 1960s helmet logo.
