Hello, I am 'Marvelous Marv', founder of Marvelous Promotions. I retired from the Detroit Police Department in 1986. My career as a police officer was from 1973 to 1986. Most of my duty was at the 7th Precinct and Tactical Services Section. I like to collect patches and badges especially ones from state capitals. Contact me if you are interested in selling or trading - Marv mailbox@marvelouspromotions.com.
