I think I've got these right. It's difficult to determine the colours exactly from the image. Top left is Scott # 1245 issued 1976 Top right is Scott # 1250 issued 1976 (Colour given as red orange) Bottom left is Scott # 754 issued 1962 (Colour given as purple) Stamp bottom right is Scott # 194 issued 1926 Non are anything special, very common.
