1935: Silver Jubilee

One of the extensive George V Omnibus editions of a common design celebrating his Silver Jubilee.  Issued May 1935 in Great Britain and spanning across her 54 colonies and four dominions coming to a total of 249 stamps. Collectors of these sets enjoy finding printing errors and  varieties such as extra flag poles.

On the card the fish basket is deep purple as is the clothing on the arm upper left. The card is of Scots College in Rome a seminary for the priesthood for the dioceses of the Catholic Church in Scotland. There are 20 stained glass windows created by Giovanni D'Aloisio. The one shown is behind the altar although the postcard cuts off the whole scene which includes the fishing boat. The full version can be seen on the header of Scots college's Facebook page. On the right is the miraculous catch of fish, the disciples are called to become fishers of men. On the left it says Ecce Agnus Dei - Behold the Son of God. The photo on upper left is of the Theological Library
