Friend Shawna, for some bizarre reason, started hunting up old 1970s catalog ads, and before I knew what was happening, I was elbow deep on a blog with a ton of vintage ads, just howling with laughter.
STRETCHY SEAT! Bwahahahaha.
If you want to see these and many, many more (with the hilarious commentary on the ads), trot yourself over tohttp://beccalou.wordpress.com/tag/vintage-ads/
You'll be glad you did.
Getting down to business...stretchy seat...*shakes head and wipes eyes*
