Explanation on back reads:

The Wild Goose Studio

St. John Cross, Isle of Iona

This, one of the first stone high crosses was a sculpting achievement;
it assimilated metal working, devised a ring to support the huge 7' cross arm, and effected a theological statement.  
The ring, a simple symbol of the unity of all things, a concept dear to the Celts, was from now on, to distinguish the Celtic Cross.

Design by Mark Joyce
Cast by hand in Kinsale, Co. Cork, Ireland.

Q. How are the Studio's designs made?
A. All Wild Goose's work is handmade by skilled craft-workers using a cold cast method. Each piece has a shell of pure cast iron or bronze backed by a resin and ceramic core. Any variations in finish are part of its appeal.
