Something a little different - this is a framed sheet of unformed 'Jacob & Cos Cream Crackers' tins. This design of tin typically dates from around the 1930s and has a small, collector's following. For whatever reason this particular sheet escaped the factory's forming press and has found it's way behind glass, in a frame, giving it a very 'pop art' feel. 

I suspect that the sheet 'enjoyed' a period of exposure to the elements before being framed as there is surface corrosion appearing on the upper section. The frame itself looks to date from the '60s/'70s and has slight scuffs to the corners and along the outer edges. 

The picture measures 54.5cm wide, 81cm high and is 2cm thick.
