I must admit, I was a little surprised to learn Victoria's Secret was around in 1977. Evidently, they started that year in a San Francisco shopping center. They also put out a mail order catalog in '77 which has been lovingly scanned for your viewing pleasure at Yeeeeee.
You may recognize the model in the picture above. That's Melody Anderson from Flash Gordon, who was also featured here in a Foxy Ladies post. I don't know about you, but I find that rather interesting.
