I think your idea was fantastic, but am not surprised you received such notice about Mickey and Che. If I drive about an hour from my home everything under the sun is in the shape of mouse ears. As for Che - I saw someone driving with a Che picture sticker on the rear of their car a couple of months ago. I thought... hmmm someone from the Ayn Rand Institute needs to come up with a good sticker I can add to my vehicle if I want as well.
Once again, good try! Keep up the use of an excellent imagination! :)
