I made these drawings with ecoline.  You see the beautiful landscapes of Amsterdam,  the flowers,  Volendam and while skating with windmill. 
On the back of the card you have a recipe. Amsterdam,  its a appeltaart on a boat. Volendam, its a haring, we eat it raw with union. And on the plate you see boerenkool met worst. I'm sending them on a a5-10x15cm and 100gr paper.
You  can choose the 3 cards you want and you get the one with the flowerfields for FREE!
