found bench drawings

Out walking the other day I came across this wooden bench in a secluded part of a local park.

It's only when I decided to have a quick sit down that I saw these black marker pen drawings on the table top. The bird poop suggests the drawings have been there a while.

Thought the tag was mysterious: 'GN MOOW' 

...then figured it out as I moved around the table - "MeOWING' :-)
