Charles M. Schulz pencil, inks, and lettering credits come from Schulz himself in an interview with Shel Dorf, in Comics Interview (Comics Interview Group, 1983 series) #47 [1987], page 15 and in Schulz and Peanuts: A Biography by David Michaelis (Harper, 2007 series), pages 161 and 167, as reported by Jean Paul on the Comics History Exchange page on Facebook, August 13, 2015.
The artwork for this issue was done by several artists and Schulz's work is hard to determine. Michaelis states that Schulz drew the climactic panels for the story.
