The series of special promo games will be extended by a further game. A Popeye with the imprint "Club de Vacaciones" was discovered.
This "brand" was (and still is) a famous holiday club (like Club Med in France), which is based in Spain. The owner tells me that her mother worked in this club in the 80's and that it was given to her on her 10th working anniversary. So I suspect that these were only promotional games for employees. No idea how many of them were made.
