Antique Mission Arts & Crafts Salem Bros NY Slag Glass Lamp

This beautiful caramel colored slag glass lamp is signed Salem Bros NY. Measures aprox 21" tall, has a 12" square shade, base is 6 1/2 square. No chips or cracks in the glass. On the inside one of the tabs that holds the glass in is missing so if you're moving it around one panel wants to fall in from the top but when it's sitting in place it doesn't fall in easily or anything. The lamp has a real nice pull chain socket and is working but there's a spot on the cord frayed, should be wrapped or rewired.
