Postcards purchased at the Miffy exhibition at the art museum! I've kept them in a file since I bought them. Please check the images (7th, 8th, and 10th) for details, but there is a slight indentation. I think it's not very noticeable, but I've included it for your information. Please purchase if you understand the above. I will put each postcard in a sleeve before shipping. #Miffy #DickBruna #Postcard
