Artist Sara Sandoval must have practiced a long time to be able to scribble out a portrait like this of Eminem on name tags. It looks like random at first but then she puts them all together and voila! Hello, my name is… Slim Shady! Her latest portrait, done similarly, is of Post Malone done on priority mail stickers (Post on post, get it?):
These remind me of those "draw by grid" puzzles.
