Nice 32.5" x 11.5" folded color chart/poster titled "Frequency Spectrum Of The Electronic Industries" showing representative electronic tubes and devices that operate at various frequencies. I think this was a General Electric compiled chart (it has a GES-3258 number on the top right corner and mentions them in the credits on the bottom). It shows many pieces of electronic devices and what frequencies they operate at. Some of the devices shown are" X-Ray tubes/screens, germicidal lamp, photocell, UHF tube, TV set, SW receiver, radio, PA system, mercury rectifier, power oscillator and more. It is in excellent condition with light marks and edgewear and a little wear at the folds. It is not dated but the address at the bottom does not have a zipcode so I assume it is pre-1965. Will be shipped folded. NOTE FOR INTERNATIONAL BUYERS....I am not responsible for any taxes on the item or delays in customs.
