Artichoke flowers on magnets

In Turkey it's a tradition to give the guests a small gift or sweets/candies as they leave the wedding hall so that they keep them as a souvenir of the wedding. My friend's father is an artist and they thought it would be a good idea to put some of his paintings on a magnet and give them to the guests. I don't know if they are called like this in English but I definitely know that the colours are fantastic.
