I found this thread only just now - but I have just bought "Lettes from Father Christmas" two weeks before Christmas (a gift to myself

) and am delighted not only by the pictures but by the lovingly decorated letters, written in such beautiful (even if purposely wobbly) writing, and amused by the comments of North Polar Bear and Ilbereth the Elf (interesting name!!)
It must have been wonderful for the children to get these letters. I wonder how long they really believed in F.C ?
For any who haven't seen it, I try to attach a scanned facsimile of one of the letters
edit: it didn't work, the file was too large
