WIYM: Animal, vegetable, & mineral postcard swap

You will have one partner for this swap. You will mail your partner 3 new unused postcards. One will be an animal, examples a fly, a horse, a person, a bird, etc. One will be vegetable, examples a tree, grass, flowers, etc. One will be mineral, examples a stone wall, a building, a water tower, etc. Be creative. The animal, vegetable, or mineral does not have to be the main feature of the postcard but should be in there somewhere. Enclose a note explaining your choices. Sender's choice.
