This is a very old unused black and white/sepia postcard of Bust of Shakespeare, Erected before 1623 by his family, Stratford-upon-Avon Church. I have no idea of the exact age of this card, but it looks like it is from the early 1900s. Apart from minor scuffing to some corners and edges, the card is in very good condition -- no creases or obvious marks.
