The third one was design by Matthew Dunn for the 75 anniversary of Avery Dennison Corporation. I chose this design, because is so unique. I like how the 7 has that folded effect. I also like of the 5 is form by the negative space.
This looks like a museum floor tile where they put the directions to a certain exhibit which I think is really cool. It stands out against the normal brick, and is eye-catching whilst also being small and not really a big deal.
