Mkay, I'm just gonna start by showing some logos I've done in the past...
LOUISVILLE SHOCKERS (Minor League Football - Check sidebar for info)

CAPE CORAL JELLIES (Fictional Team I made up for my Florida Coast League Project)

NAPLES ORANGES (Florida Coast Leage Project)

LOS ANGELES SOMBREROS (Draw Brawl Competition)

Enjoy these, I should get some word art up later.
