Love it!
Gosh I love that great old TV shop ad material. I have some myself but nothing that nifty for sure.
Soooo. GE picture tubes are 100% brighter?
Than what? Your zero emission tube with an open heater???
Classic "unfinished claim".
That piece really brings one back to another time when:
Great art showed up in everything including TV shops.
People primped themselves in the mirror while dropping off their TV for repair,
When unfinished claims were all the rage in advertising.
