Clearly fragmented for the art market. The leaf is glued to a board and framed so only one side is visible. 

From McGill's description: "The large historiated initial is the first letter of the word Salve and contains the Virgin, in a blue-coloured mantle, protecting with it seven, white dressed, kneeling monks. Farquhar-Montpetit suggests a Cistercian origin. The figures stand on green ground while the white, scroll-containing initial lies on a square, with gold leaf contour.
A two and one half quarter border occupies part of the upper, the whole left and almost the whole of the lower margin. It is foliated, containing tweesting acanthus leaves in blue, light-blue, green, red, white and yellow colors. A large number of bezants, single or in triads, with short yellow comet tails, surround the decorated borders or stem from the foliated elements of it. From a green bud, in the lower border, stems a male head, seen from the front, wearing a blue hood-like head cover."

According to Holland, "the style, decoration, coloring and dimensions point to a common source with CDN-Mlr MS 0064, described by Leesti (Liturgical Manuscripts, p. 35, no 7). MS 0065 has been described by Farquhar-Montpetit in "Canada Collects the Middle-Ages," pp. 73-74, no 77."
