I was looking for "funny vintage ads" in Google and came across the clever corset ad I used to make my new banner. The best part, is that it's on eBay if you want a copy of the original (pre-Mom O Matic bastardized) version.
The seller, AntiqueandVintageAds, actually has a few funny ads for sale;
An aspirin that makes you gay when you need to have more fun.
A gasoline that renders you impotent so you can cut back on "traffic boners".
Or a company that encourages you to flee on the bus if your family is too goddamn messy.
