I found the answer.
"You can take the boy out of the country but you can't take the country out of the boy", in The Oxford Dictionary of Proverbs, the proverb is attributed to the book:

1938 "B. Baer" in Baer & Major Hollywood

Hollywood By Baer & Major
Sports writer, humorist and cartoonist Arthur "Bugs" Baer put together a book in 1938 with Henry Major called Hollywood in which Major did caricatures of the celebrated players of the
day and Baer wrote accompanying humourous commentary.
The book was released in a limited edition of eight-hundred copies.
