The Cathedral of Saint John the Divine had a problem with dog poop and dog owners not cleaning up after their pets. Handling the issue like a pro, the church called on the services of design firm Pentagram. Designers created messages and boards with typography and tone to match the holy commandments. Pentagram tried to make the boards beautiful, durable, and with humorous catchphrases to get the message across.
This led to boards with letters like “Waste Not Wanted” and “Leave Not Behind”, until they finally found the winner “Thou Shalt Not Poop.”
