This pen work snuff box was by George  Cobb. he was associated with pen-work decorated wooden snuff boxes, active from 1820-1860.
This snuff box is decorated in.pen work,  which is fine ink drawings applied directly to the snuff box and then varnished over.
The snuff box has an interesting picture on the lid of three gentlemen sitting around a table drinking. They are holding goblets, sitting on chairs and a barrel. There is a clock on the wall a window, shelf and  a fireplace. There looks like  a snuff mull on the table and maybe a pair of glasses dropped on the floor.
There is some writing on the box says but I can't make it all out. It starts with 'It is the....'
They look to be having a good time. 
The box has a hinged lid, remnants of the lining to the inside and some pen work decoration to the sides.
The box measures 9.2cm w x 4cm d x 3cm h.
