Postcard sent to Heleen (the Netherlands), made of a box of two-tips felt pens. She published it here, so I could see the cancellation (I was very curious about!):
Five years ago, I uploaded a similar postcard to the blog, also sent to Heleen. It was the third post of Mail Adventures.
I have learnt a lot about mail and mail art since then. At least, I have been upgraded from colour pencils to felt-pens!
