Guys! A new development in penglish studies has been made!!
Searcher Joe P. Dophile has just discovered the oldest record of penglish to be found yet!!
The comic-strip "Krazy Kat" (sic.) features a native locuter of penglish as it's main eponymous character!

This is a HUGE revolution for penglish studies as it pushes the apparition of penglish back to the 1910's, invalidating the leading theory of penglish as a sociolect appearing alongside the counter-culture movements of the 60's. Penglishists are currently debating wether "Krazy Kat" 's language should be considered penglish or proto-penglish.

Pic. Related is a "Krazy Kat" comic strip from 1921. Interestingly enough, we can see that locuters of penglish suffered similar repulsion then as they do today.
