Signs, Symbols & Omens. Good subject this one, lots of scope for variation.

Crucifix, Probably the most common symbol in the Christian World: Ironically this was shot in Dachau Concentration Camp.

The Masonic Trowel.  Masonry uses signs and symbols in its workings

The plea in many of the worlds poorest countries is "one dollar mister" It is the amount that many people have to survive on.

The SIGN we all HATE!!!!
