This is a wonderful series of Scientific German Educational Charts that were created in the 1950s and 60s, and which are produced to this day by the original printing company. This manufacturer has been internationally recognized for producing scientifically accurate educational charts since 1929.
These charts have been reissued using the original film and same methods as the first printing. They are printed without inscription for university study and aesthetic purposes with special attention paid to anatomical detail and accuracy.
They are mounted on linen canvas stretched on wooden rods for display. Each measures 44.5 inches tall by 32.25 inches wide (85 cm x 120 cm), and comes with a nylon cord strung through the top wooden rod for easy hanging.
They come rolled and are shipped in a sturdy mailing tube.
