The yellow castle wall part in this auction (not mine) (URL) to have the black lines pattern inverted. Is this known or just a printing error? Chris (23 years ago, 30-Dec-01, to lugnet.cad)
(...) The wall part included in set 6074 does not have the black lines pattern inverted. I have no idea where this auction part comes from. Damien (23 years ago, 30-Dec-01, to lugnet.cad)
