This set is a bit of a mystery to me. I have only been able to trace these meagre few copies of the set thanks to a Belgian submitter on Catawiki; I don't even know how large it is. Also, since the captions only mention the series name, this leads me to suppose that other Supermarionation series featured in this card collection as well. What intrigues me most though, is the subject matter of the pictures: some are behind the scenes shots, some seem to be specially posed for this series.
I changed the numerical order to emphasize certain similarities.
