Hello Tzvetomir,

I’ve checked the images you’ve shared and In my opinion you had a great idea. I believe it is very interesting for a buyer to better know the artist behind the piece he/she bought. And It opens a communication channel too! I usually send a letter to buyers that buy my art without knowing me in person.
We are artists, emotions are very important for us and communication too, plus the buyer is buying a piece of our soul. It feels right to let him/her know what’s behind it!
