A quick drawing I made this afternoon.

Find the Jewel! The H.G.CO. b-hive signifies the commons, the u/m 731 signifies the more exotic, the OB signal signifies the mud and the spool signifies the miscellaneous.

Unfortunately, the scanner exaggerated every smudge and erasing on the page, as well as the writing on the back! Whoops!

Enjoy.
