Marine Corps 20” x 15” Guidon Design 2015-D2-M4. The framed guidon features an embroidered single-sided guidon sewn onto the bottom acid-free mat. The Marines guidon has triple acid-free mats. The top two mats are cut into the shape of the guidon and an opening for each object. The bottom mat is used for mounting objects in the openings. This guidon design features five object openings. The first opening is for the guidon. Within the guidon’s swallowtail is an opening for a patch or similar size object. Three openings are beneath the unit guidon’s opening. The object openings from left to right are for a challenge coin, a name plate, and another challenge coin. The design also includes an open V-groove immediately around the Marines guidon and the other objects. Surrounding the mats is a traditional 2” wood tone medium brown frame with metal corner caps. The glazing for the frame is 99% UV protected acrylic. This frame selection is very popular with the military.
