Printed by Marées Gesellschaft - stamp bottom left corner - Blindstamp Ganymede and Eagle inside oval lower right corner (R. Piper & Co. Munich). There are no rips to the (thin) paper - I believe the 'foxing spots' you see on the paper is on the original watercolor(?). This was found in an oblong folder with plastic front, leather edging and cardboard back with opening on the top. I don't think the print was ever framed.
