Where to find free large downloadable images?

[cookiemonster80]

This is my first time making custom t shirts- I'm doing Mickey Mouse shirts for the family trip this Christmas- just really basic Mickey Mouse ears with some text- all of the downloadable images are coming across as too small to use for this. Where can I find an image that is large enough? I'd even pay a few bucks for it if I knew it would work- and how large should it need to be?

TIA

Yeah, you can't find it b/c it'd be copywrite infringement. Some etsy sellers can get in a lot of trouble if their "ears" look a little too identical to the real Disney ones.

I suppose you could always scan something from a real Disney coloring book & try your hand at photoshop.
