St Mark's Square, Venice is an original drawing realized by Francesco Zanin in the 1877. China ink, watercolor and tempera on cardboard. The artwork is glued on brown paper. Hand signed and dated on the lower margin. Handwritten dedication on the lower left margin. Good conditions except for very light stains due to the time. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
