King Features Syndicate cartoonists did Earth Day strips today. Dave Astor's got the story.
In the Washington Post, one can see Mutts (themed strips all week since last Sunday), On the Fastrack, Curtis, Hagar the Horrible, Amazing Spider-Man (just a blurb), Blondie, Mark Trail, Dennis the Menace, The Family Circus, Frazz, Mother Goose and Grimmm, Sally Forth, Beetle Bailey, Zits, Prickly city, Judge Parker, Baby Blues and Zippy the Pinhead.
In the Washington Times, one can see Crock, Mallard Fillmore and Bizarro. Funky Winkerbean just had a sign on the school's notice board for its Earth Day strip.
