Framed Shell Art Print After Knorr c 1773 Engraved Paul Küffner Coastal Decor Framed coastal wall art print featuring detailed antique-style shell illustrations after an original circa-1773 natural-history engraving by Georg Wolfgang Knorr, engraved by Paul Küffner. The image is marked "Ex Museo Houttuyniano," referring to shells from the collection of Dutch naturalist Martinus Houttuyn. Soft neutral matting and a slim gold-tone frame give it a classic look for a beach house, bathroom, study, or gallery wall. #Minimalist
