3 Logos: The Pillows, Zelda, and The Sims 3.
3 Pokemon: Pikachu, Wobuffet, and Shuckle.
These shirts are fun. Wanna know why? Because the images on them are stencils. That means you can change the main color as normal, but the faces and logos stay the same.
The Pillows. This isn't their logo, I think, but it's a logo that shows up in the anime FLCL. It's my favorite band.
Zelda! It's the Hylian Crest.
And The Sims 3. Duh.
Example of CASTing:
And the Pokemon. Here's Pikachu:
Forgive me if the image quality is a bit low, Photoshop seemed to think I wanted it to automate saving them at low quality instead of medium-high.
They're grouped together, so you'll find the logos and pokemon under one "shirt" each in CAS.
The logos belong to their respective owners, and Pokemon are the property of Nintendo and Game Freak, not me.
