I seem to have anatomy on the brain. Here are a few large and amazingly detailed teaching charts that I have for sale.
Published by AJ. Nystrom & Co. Chicago 1918-1922. American Frohse Anatomical were originally done by Franz Frohse (University of Berlin) @ 1910 they were revised by Max Brodel (John Hopkins University) and copywrited from 1918 thru 1948.
When published their richness of chromolithographic tone, led many to consider them to be the finest such charts in the world, far surpassing today’s rather flatter images. The image size is 66 x 41 1/2 ”, mounted on original linen 79 x 41 1/2”.

Do you know when these were printed? They seem much more saturated in color than other photos I have seen online.
