Vintage 1970's Sony Advertising Color Changing Lighted Sign

Description

Vintage 1970's Sony Advertising Color Changing Lighted Sign.
The sign changes from green to blue with white in between.... This sign is awesome!
The sign does have some imperfections. The chrome surround does have some surface rust on the front edge (see photos), and some glue appears to be coming loose above the S and Y on the chrome surround (see 4th photo).
There is a small 1-1/2 dent on the top of the chrome above the "S".
Very displayable, and a great looking sign.
I bought this sign from a man who owned an Electronics Store in California until the early 1980's. Very Cool.
Sign measures 21-1/2 inches x 7 inches.
