MLB will put out a contract for bid. This contract may be for hats, bats, TV rights, etc. Companies that would like to do business with MLB bid on the contract. MLB selects the bid that will be the best for them (almost always the highest bid) and awards that company the rights, called licensing agreements, to produce the hats or bats with the MLB logo or team logo. Click on the 'MLB Suppliers' link on this page to see who MLB awarded licensing agreements to in 2005.
A logo artist is a person that designs a logo. It is just another name for logo designer.
In MLB and NCAA, at least, all team caps must have an official team logo on them. Most wear their team letter(s), but logo's can be used, like the redsox using the "2 redsocks" logo on their caps this year. The SD padres wear camoflauge uniforms for Sunday home games with their regular logo/letters on it. All uniform/caps must be approved by MLB/ NCAA before worn on the field.
Update: MLB is Major League Baseball. The logo details: MLB recognized Jerry Dior as the MLB logo's original designer, said Commissioner Bud Selig in a release. With the recognition comes the answer to ? that has puzzled: which player is the silhouette based? "People said my design was based on Harmon Killibrew, but it wasn't," said Dior. "Mine wasn't based on anyone--just nondescript figure with a bat." "I didn't model it after any one player," Dior said. "It was intentionally ambiguous in every way, including righty vs. lefty."
