2 Registered Letters from Joe De Yong to Joe

2 Registered Letters from Joe De Yong to Joe De Yong
a) Opened, dated November 25, 1949. In the envelope a letter from Walt Coburn to Joe about working on a western comic strip. A reply from Joe (handwritten copy). All seems well. The registered letter comes in with a letter Joe wrote to himself in case something bad happened to him while visiting Walt at his home. He is afraid of losing his titles and story lines. Basically a copyright letter.
b) An unopened, sealed letter December 17, 1949. Contents unknown still.
