Okay the first thing I thought of was my little collection of rocks, shells and other artifacts.  I usually pick up a rock or seashell on any trip I take and some of that is included in this shot as well as some local finds:  a sharks tooth found in mined phosphate, here in Polk county Florida and a native american arrowhead found by my brother in law in the woods of Lafayette county Florida as well as driftwood out of the Suwannee river here in Florida.

 Anyway enough with the description you should find a Y, some O's and a couple of V's there is also a questionable C  ;-)
