Erhard Beitz has made a beautiful picture of a plant with the Latin name "iridáceae". We are not sure which Iris this is but a good guess could be it is a "gemánica" as Erhard Beitz is from Germany. The print is an etching, drypont.
Picture area: 9*6 cm (2,3*3,5 inch).
Paper size: 19*15 cm (7,5*5,9 inch) (not shown in full on the screen).
The print is signed and numbered by the artist, and the edition is only 15.
