I love vintage spice tins...the interesting graphics and bright colors. They add a bit of old-time charm to the kitchen. They are small and easy to display which is a plus in my "cozy" kitchen. Mine are displayed on the window shelf above the sink.
I must confess I did not collect these one by one. I cheated a bit and bought them as a set on Ebay. The seller put together a nice collection of colors and sizes for me.
Vintage spice tins can be found at garage sales, flea markets, and vintage/collectible stores. Prices vary from a dollar or two on up, depending on the age and rarity. What do you "show off" in your kitchen? *smile*
