I love Vintage Advertisements, and I'm always looking for vintage ads at fleamarkets and on the Internet. I also love cats, since I have three. Don't judge! I make sure they're not around when I bake. No chocolate for cats. It's poisonous. Thought I'd share these Black Cat Ads. One is for Yeast and the other for Baking Powder! A Baker's Delight! Enjoy!
