This is the exact letter that made Gary Halbert a millionaire in 1971.
It was one page, sealed in an envelope, selling them a “Coat of Arms” picture and report based on their last name, and it peaked at making 20,000 sales per day (and these were physical mail orders) 😮
This particular letter was sent to every “Macdonald” in the phone book across the United States:
For $2.00 (in 1971) this is what was sent back to you:
1.) A coat of arms picture of your family last name, you could then frame it if you liked. Like this (without the frame, it was just sent to you on paper):
2.) A small report explaining the coat of arms: (h/t to @eston_esau for taking this pic of this in his grandpa’s house)!
