3'x5' Nylon Police Mourning Flag. In remembrance of the brave men and women who have lost their lives while on the call of duty we also offer fireman mourning flags and police mourning flags. Both of these flags consist of three vertical stripes of purple white and black. In the center of the fireman mourning flag lay a black Maltese Cross with the words "In Memoriam" above the cross. The police mourning flag offers a badge in its center with the words "In Memoriam" centered above it. Let their memory live on not only in the hearts of those they have touched but through a beautiful display such as these flags.
