Possibly a bit late, but normally I read this book in xmas eve. To the english subsimers, do you know it?
My father bought this possibly in 1985 or 1986 for me, in a second hand book shop. It is a portugues edition, but all the places plus houses drawn are english ones, the last place santa visits is
Buckingham Palace,. The first edition is from 1973, the author is Raymond Briggs!
