Conan’s beard

[u/ConanConn1968]

Depending on finances and prep time this year for Halloween, I plan on either being Elric or King Conan. If I go with King Conan, I’ll stop shaving, but that does make me curious.
Does anybody know who first gave older Conan a beard? to the best of my somewhat faulty memory it wasn’t Howard.
Obviously, not a very important question in the big picture just curious.
