When Charles Schulz was alive, he was a much beloved Santa Rosa community member. The museum that bears his name continues to share his neighborly spirit with a birthday celebration honoring the renowned cartoonist’s centennial. At the Happy 100th Birthday, Charles M. Schulz! event, performers from the Roustabout Theater’s Apprentice Program will sing “Happy Birthday” as well as selections from their holiday presentation of Irving Berlin’s musical White Christmas. Meanwhile, MazeToons creator Joe Wos will offer cartooning performances, and there will be free giveaways and cake, too. The party happens at the Charles M. Schulz Museum in Santa Rosa on November 26, 10 a.m.–5 p.m., with cake and music at noon. It’s free with admission: $5–$12 or free for ages 3 and younger.
