Reproduction of a vintage educational diagram featuring pleurotus ostreatus, or oyster mushroom. The original art used for this print is from the text “Atlas des champignons comestibles et vénéneux (Atlas edible and poisonous mushrooms)" by P. Klincksieck (1891). The pages have been scanned in and retouched to ensure the highest quality reproduction possible. The art is digitally printed on high quality acid free and archival matte paper.
