"Lookin' Up" is the all-time most popular greeting card I've done over the course of 27 years. Something about it seems to click with folks, it just keeps on keeping-on like that energizer battery ad with the rabbit beating a drum. It has been on shirts, magnets, greeting cards, coffee mugs and note pads. It first came out in '95, and the publisher's catalog that just came out ran it as a full page image. Go figure ?
