All photos show the item unframed. The first 4 show it with its current mat, the remainder are without the mat.
It is currently affixed with 2 hinges to a poster board backing. There is uniform overall toning... Somewhat lighter toning under its original matting. There is also some remnants of creasing (now flattened, likely from the original pressing) most visible on the underside that is largely hidden under the mat (see pics). They form part of the description. Other destinations to be determined.
