The particular example we are considering today comes from the second half of the 19th century and is found within the Franciscan convent of Sao Francisco de Lima located in Peru -- a former Spanish colony within the continent of South America. It is made from an azure or cerulean blue silk that has been decorated by gorgeous, raised silver thread embroideries -- the heavier embroidery style being quite typical to vestments of the latter half of the 19th century.
In the midst of both the front and the back of the chasuble we find explicit Marian imagery. In the front, the classic "Ave Maria" symbol made up "A" and "M" and topped with a crown (further surrounded by lilies); on the back, and image of the Virgin herself, the Virgin of the Miraculous Medal.
