Here is one of a set of Ship Series themed Delft tiles. These tiles were used as coasters on KLM flights in the 1980s and given away to the business class passengers as souvenirs. This one features a double masted hay barge with multiple sails. It is still in the original cardboard sleeve with information about the history of Delft polychrome work. However, the certificate of authenticity is missing. The tile is in new condition with no chips or cracks, and the blue velveteen backing shows no wear. I have seven from the set, the full set has nine tiles. This one is numbered C5 on the cardboard sleeve. I am listing the seven tiles individually. I am happy to combine shipping and negotiate a discounted price if you buy multiple tiles.
