Issued for a fee to any firefighter or retired firefighter in the state of Colorado. At bottom is a blown-up version of the central logo.
UPDATE: (February 13, 2003) The plate at left differs from the plate at right in one way. The plate at left has the word 'firefighter' spelled out as one word. Observant Colorado collectors know that firefighter plates have been issued since 1998 or 1999 and into the 2000 license plate re-design all with the word 'firefighter' as 'fire fighter.' It seems that at some point in late 2000 or 2001, the state must've actually consulted a dictionary and found the correct spelling of the word 'firefighter' which was soon changed on the license plates. Neither type is rare, but it's extremely unusual for a state to make a spelling error on a license plate. I'm in the process of figuring out when the spelling was changed with reference to plate numbers; I've seen it as two words on plates as late as the EJY series, and one word (above) on #599 EWN. (:
UPDATE: (June 24, 2004) I've verified 'firefighter' as two words on xxx EWG, so the cutoff is in the EWx series.
