Did these desings long ago with the aim of rising some money for a horse club that wasn't doing very well. These were sold as keychains, magnets and stickers and I remember raising almost 100€ by selling them at a convention. It wasn't much but it helped them enough to get some stuff for the horses.

At the end everything went well, they got to face their situation and now they are doing quite good! ^^

I've seen that are some associations in my country that rescue horses and they normally need food, medicines and other stuff, so maybe I'll put these on sale again someday ^^
