Hit or Miss: TV Lens
In the 1940's (and very early 1950's) TV screens were still quite small, 12" was leading edge in 1950. In order to make the image a little more impressive, especially when sat across the room, a number of TV magnifying lenses were available. Hit or Miss, you tell me?

Television Lens Fires
Once again it is necessary to warn dealers of the possibility of fires being caused through the concentration of the sun's rays by television magnifying lenses on to inflammable materials in shop windows or showrooms. The current journal of the Fire Protection Association devotes space to this hazard, which is particularly dangerous at week-ends when the shops are closed. Lenses on display in windows should be backed with a sheet of opaque non-inflammable material, says the journal.
