C.Martinu of Spain seems to have been at his zenith in the 1970s, having started out in the 1950s. The majority of his pieces seem to focus on animals, ducks, monkeys, etc...however, he was also the earliest of the Spanish tiki mug makers and many of his designs seem to have been carried over to Arte 4 and Porcelanas Pavon. Spanish tiki mugs with his signature on them will be among the earliest from Spain.
