Here's a colorful soccer / football themed backpack. It's probably nylon-weave, and all done in bright orange, yellow and green. Notice how the "SEGA" logo is slightly raised, it is likely plastic or rubber. The Sonic stock art is placed so that it looks like he's getting ready to kick the ball. Notice the copyright near his foot. (and the lack of "Sonic" written anywhere on the bag, though it is official.)
