The announcement in S. Maria sopra Minerva is an original drawing in pencil on paper, realized by Giovanni Fontana. The state of preservation of the artwork is good except for some stains. Passepartout: 35.3 x 28 cm Hand-signed in the lower right margin. 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
