These are the bonus stickers - my favorite artistic medium recently. Originally it is an advertising material, something one receives in supermarkets, fuel stations and convenient stores usually for every 10 euros spent. A collection of them, attached to a card, gives an opportunity to buy certain products with discounts. Though many people think that they already have too much stuff and just throw them out. I don't think the stickers deserve that. I prefer to give them one more chance - in my sticker paintings.
