2 VINTAGE BELL LABS WESTERN ELECTRIC WAFER PHOTO MASK SHOP GLASS 1981 RETIREMENT

Description

This is for a lot of 2 vintage Bell Labs Western Electric photo mask for integrated circuit wafer manufacturing. From the 1980’s as were many of the items from this collection. This item would look great framed and lit from behind. Not sure what this one is. It looks more like a building design rather than a circuit board. The 2nd one was made for the employees retirement. They are both 5” by 7” in size. I have more of these and will be listing them as well. Some much larger. Will combine shipping.
This came from the estate of a retired Bell Labs engineer, obviously.
Bell Labs Western Electric Wafer Photo Mask Glass. Condition is very good overall. This one is just orangish and white so you can see more normal wear on the glass. For parts or not working. This has been in storage for many years. It has minor scratches and the like on it from use but otherwise it looks great. NOTE: Also including a photo of the box label it came in with others however the box is NOT INCLUDED.
Shipped with USPS Priority Mail or similar.
