The letters "SPQR" are often seen in reference to ancient Rome... SPQR is an abbreviation of the
phrase "Senatus Populusque Romanus" (freely translated as "The Senate and the People of Rome")
and signifies the power and unity of the government and the governed.

SPQR is found on ancient Roman coins... archways... mosaics... building inscriptions and plaques...
banners... statues... military regalia... and in this one very interesting case, on a modern poker chip!
