Animal Friendly Optional Graphics


Many states in the US (but not all) offer these extra-cost option graphic plates. These promote pet-related themes such as general animal welfare, adoption, and spay/neuter programs. The extra fees associated with them are sent to animal welfare charities for one of those purposes. I am a big proponent of animal welfare, so although I do not generally collect optionals, I have included this section in my collection.
