The Argyle Sweater, a comic panel by Scott Hilburn, has risen to the top of the cartoon class in two short years. Now Chicago-based Recycled Paper Greetings is upping the ante with the launch of 12 birthday and just-for-laughs cards designed by Hilburn. The cartoonist’s sense of humor skews towards the edgy and bizarre, but Hilburn has a large fan base, the result of syndication across more than 200 newspapers in the United States. Hilburn has also put out a book of comics and a calendar under The Argyle Sweater moniker. A card retails for a suggested $2.59. More information can be found at www.recycledpapergreetings.com.
