Very scarce official Executive Protective Service officer badge, measuring 2.5 x 2.75, featuring a raised patriotic eagle emblem against a blue enamel background near the top and an image of the White House raised in low relief on the main body. Reverse bears the engraved serial number 150 and a Blackinton manufacturer’s stamp. Historically desirable, this is actually an early uniform division secret service badge. The low #150 serial number indicates its use when the executive protective officers were known by that designation instead of the now more commonly known secret service uniform division.
