I loved the numbers on your post (so many 3s :D), just before I clicked upvote and ruined it all haha :P

Anyway back to your post, I really love this piece of street art! Reminds me of the artist who repairs walls with lego!

Also reminds me of the painted chewing gum marks in High Barnet (I used to see it all the time when I went to school there!).

Found this blog about it :) https://bigbeautifulads.wordpress.com/tag/chewing-gum-art/
