Purpose: These larger Perspex sheets were manufactured from the late 1960s to the 1980s to serve as the translucent faces for illuminated outdoor dealership signs, roadside hotel markers, or breakdown station lightboxes.
Size is 30cm square.
Condition is fair for age. if you look at the pictures you can get a good idea of condition, there is tape on the edges which was probably done when the panel was in the light box. , having said this it would still make a nice display item
