Brand Names Foundation "Competition" Ad

This was an ad ran in Reader's Digest in 1966 asking readers to "write in for a free booklet." "Writing in for a free booklet" was the "email signup" of the day before the internet. You would write a physical letter ➡ Send it via Post Office ➡ They would send you the material and collect your name/address to put on their marketing list. There was so much more work involved in creating a "customer list" back in the day!
