Four Color #978

In "The Mystery Letter," Pepper finds himself unexpectedly drawn into a quiet mystery when Lolly asks him to deliver some papers to Mr. Quimby at a men's club on a Saturday. With Lolly too shy to go inside, Pepper takes on the task—unaware that this simple errand might lead to something far more intriguing than he expected. Written and illustrated by Pete Hansen, this 1959 Four Color adventure blends everyday charm with a touch of intrigue, all brought to life by Hansen’s distinctive art on the cover and inside.
