I found this botanical matted artwork at auction! Entitled Canna Denudata Var and PV 1 mark opposite corner.  Features large green leaf with orange floral shoots. The print is hand colored, possibly hand colored stippled engraving.  Large matting measuring 32" by 24" while the print is 22" by 17". There are some wrinkles in the print as shown in images on an angle. Also, the bottom shows water staining to the matting.  Scuff marks in the matting top section as well as minor scuff marks upper left hand corner of the print. Nice old botanical print. Also made in Italy marking on the back.
