Picked these panels up in a lot of miscellaneous salvage items at an estate sale.  Not sure if they were used before.  They are all quite thick and could be used for a shelf, table insert, replacement glass etc.  Perfect for the restorer.

Lot includes six panels as follows:

12"x12", 3/8" thick finished bevel clear - in the picture there are protective cork stickers on the panel which will need to be removed

11 15/16" x 11 15/16", 3/8" thick finished bevel clear

4 - 11 1/2" x 11 1/2", 1/4" thick - clear, light green, brown, smoked - 1 of each color, did my best to be descriptive of the different glass shades, see pictures
