Okay, not really a "card" :)
My husband made it for my girlfriend who loves Snoopy. DH is a tad obsessed with planes, and has a couple books with templates to make these complicated paper airplanes (that really fly!). This is a Sopwith Camel: of course I said "you should put Snoopy in the cockpit" so he drew a Snoopy (seriously, he drew it freehand!), then he added the flames and the smoke. I found a Peanuts font and printed it on the marbled cardstock for the smoke, and voila!
