Which one of these is not similar to one of the others?* Illustration Friday's theme this week, as you can guess, is similar. I'm sure IF visitors are tiring of the Orange brothers, but since they're twins, I couldn't not include them in a smorgasbord of similar things...even if they are the only imaginary ones. BTW, Myrna and Spot turned out just about perfectly.
*This reminds me of Sesame Street's "One of These Things Is Not Like the Other" song.
