Do you have a friend who is a race car fan? This is the perfect digital stamp set to make a card for him. Burnin' Rubber by Pickle Potpourri makes a fun birthday card for a racer.
My card, in red, white, and black, uses a red background with some black and white checked patterned paper to accent the race flags. I've colored the image with red Copic markers and used several shaped dies for the images. You can find this stamp set here.
