Do you often forget about the difference between the Rock N' Roll sign and the Spider man sign? Well worry no more because we've solved all your problems. This wall sticker can show you the difference by correctly labelling the different hand gestures. The hand sign with the thumb tucked in, is Rock N' Roll while the hand gesture with the thumb out on the side is the Spider man sign. Like all of our stickers, this design comes in many different sizes and colours.
