I am a nut for all things round: planets, lightbulbs, pearls, globes, any sort of round sport ball; you name it. No doubt there is something deeply mystical about the perfection of roundness. But it's just fun to see a round thing.
I won't presume that the comics I like are liked by others. Here are a few that I find regularly amusing. (p.s. Please note: These are not necessarily "for kids." )
[from the Wondermark website] "Wondermark is created from 19th-Century woodcuts and engravings, scanned from my personal collection of old books and also from volumes in the Los Angeles Central Library. Most of the books are bound volumes of general-interest magazines such as Harper’s, Frank Leslie’s and Punch, but my collection also includes special-interest magazines such as Scientific American, Sears-Roebuck catalogs, storybooks, and primers."
