You are looking at this Vintage Sylvania Test Picture Tube.
Or at least that is what the box says.
On the tube it reads:
Sterling Type 8YP4
There is also an RCA Adapter on the end of this tube.
It measures 8 1/2" x 7".
I do not know if it works as I have nothing to plug it into.
If you have any questions please ask.
Thank you for stopping to look!
