Duboce Park saw some creative new sidewalk art pop up last week. Signs painted on the asphalt notifying dog owners of on-leash dog areas have gotten an upgrade, with balloon dogs, origami corgis and even Snoopy making an appearance.

No artist has signed the work, so for now, the creator's identity remains a mystery. Seen any others than what we've posted here?
