 Medium-thick flat vellum stock poster is in good/decent (B to B/B-) condition; there is a large pronounced thin diagonal crease/bend along the lower right margin, along with a 1" vertical tear in the bottom center margin (sealed on the reveres with clear tape), a few thin diagonal stress creases/bends in the lower left corner, a tiny nip tewar in the left center margin, a bit of handling wear/creasing along the top margin, a hint of edge toning/light surface dirt, a 2&1/2" diagonal bend in the upper right corner and a couple of light/thin stress bends and light handling dings hiding within the image area, otherwise OK.

Conditional issues aside, this example actually looks quite presentable.
