C-1940 POSTER Science on Parade GYROSCOPE OSCILLOGRAPH Scientific Demonstration

Description

PLEASE READ BEFORE BUYING.   I sell ONLY ORIGINAL items and NOT ANY reproductions.
This sale is for one RARE circa 1940 ADVERTISING POSTER that came from the archive of Harry Byrd Kline. of Southern School Assemblies in Dallas Texas.  Mr. Kline passed away around 25 years ago.
This poster is approx. 11" X 16" in size and is in near mint condition with one horizontal fold that is not noticeable in the scan.  I couldn't get the entire poster scanned with my legal sized scanner.
Poster reads: "A Popular Scientific demonstration SCIENCE ON PARADE, Induction furnace, see an egg cooked with a newspaper held between stove and skillet, neon tubes lighted wih no connection with the instrument. Oscillograph, see your voice and the sound of various musical instruments, Gyroscopes see the man wrestling gyroscope and demonstrations of airplane stabilizer, gyro compass, gyroscopic eye, gyro pilot, other amazing demonstrations, COMING HERE : "
Please take a look at the other posters I have for sale from the same archive. Many are not all shown in the scan because my legal size scanner was not large enough, or even close, to get the whole poster in there.
Free shipping to the continental U.S. only.
