Thought I would share some photos of my Electrical and Insulator related collection of matchbook covers. I wish I had a better camera but it's the only one I've got so please excuse the grainy in some. This first frame has matchbooks from Line Material Co., Joslyn, Eagle switches, Hubbard & Co., Seyler, Illuminating Electric Co. and Trumbull Electric Mfg. Co. Some matchbooks have products shown on the opposite sides but I could only photo the one side. Matchbook covers like any kind of advertisement boxes are very hard to find because they were usually thrown away when used.
