A handsome young man poses in his fraternal organization uniform at the studio of Edward Landsheft in Buffalo, New York. The previous owner of this cabinet card asserted that the uniform represents the Knights Templar, though I can not confirm his opinion as fact. The subject of this image is holding a sword. Note the knights head on the sword pommel. Also worthy of notice are the crown and cross on his gloves and the initials “OPK” on his belt buckle. It is unknown whether “OPK” represents the man’s initials or is related to something specific in the Knights Templar culture.
THE CABINET CARD GALLERY 
OKP would be Order of Knights Pythias but OPK might be something else. This link has good explanation of the variety of fraternal society swords.
