Invisible letters to Max 1/12

This is my new art project. It all started with my friend Max, who is something like my male muse, he told me, if he could afford it, he would buy one of my collage books every month.
So I invented this as an art project. He will get the mini books, one every month and I will send him hunting for new material all over Cologne (unfortunately he does not live in Cornwall).
So what you see here is the first of twelve, there will be one "invisible letter" every month.



















Thank you Max for inspiring me!
