Blue Collar, an actual color and a description...working folks are sometimes called "blue collar" while "professionals" are "white collar".  I am a professional at my jewelry work but as such would be a "blue collar" worker since I am not a lawyer, barister, accountant, banker, etc.   What a Native American  Tribal Chief would be I don't know...     

There is more bluring of the lines of such old stereotypes of work situations..unless it is "white collar" crime.  Blue collar crimanals would just rob a bank directly, I suppose, while a white collar thief would hack the system and download the cash to a private account..go figure!                    Reprints of the pic will be available depending on demand..LOL>
