1953 Coronation Souvenir tin by W.D. & H.O. Wills for Wild Woodbine Cigarettes.  This is a wonderful, rectangular tin in sea green with gilt trim, measuring 15 x 9 cm, with hinge opening.  It has inscriptions on the front, back and inner lid.  
Good condition with signs of wear and some scratches - witness to usage! 
Would make a special container for pens + pencils, for example!
