The mascot for the Indians was Chief Wahoo. It is or has been phased out. The present mascot is Slider an amorphous dinosaur like creature and has been my whole life. The logo was still Chief Wahoo when I was young however the latest Indians logo is just a script C on blue. From a basic search only Ebay has Chief Wahoo hats. It will be interesting to see if that move is enough, though to give the Indians credit they started this process at least thirty years ago in regards to the mascot and 5-10 on the logo.
