Charlton Swipes DC's "Practicing Hippie," Zack Barton!

Remember "Practicing Hippie," Zack Barton (above) from DC's Woodstock story, "I Found My Love at the Woodstock Festival!" Falling in Love #118 (October 1970)? As I was flipping through my new finds the other day, I came across "Do Your Thing!" in Charlton's Love and Romance #1. The guy on the splash page looked awful familiar!

Well, Charlton? What say you?!
