The Minneapolis Park Police Department (MPPD) was founded in 1887.
MPPD uniforms were issued approximately one year later in 1888.
Until 1905, the MPPD uniforms were grey in color. After 1905, their color was changed to blue. They were identical to the MPD uniform in every aspect but their buttons.
The rare button shown above is one that was worn on the blue MPPD uniform.
The photograph below shows MPPD Office John Joseph Mueller in the blue uniform circa 1905.
