I have no idea where it's from or how I got hold of it but I can make out that it is from 1976 and that the words on side are 'Dei Donum' which I think means gift from good. Here are some pictures of it, sorry I can't make out any more so it is poor quality : http://m.imgur.com/z32aeMh,pVBe5HL,HyO0v4J
