This Lladro figurine is indeed part of a series of 4 beautiful pieces. No. 1435 which is the first is titled "Blue Moon" and is 8.5" tall (and is the tallest), No. 1436 is titled "Moon Glow and is 7" tall, No. 1437 is titled "Moonlight", is also 7" tall and is almost the companion to Moon Glow as both figures are sitting beautifully on crescent-shaped moons, and No. 1438 which is the one in question is titled "Full Moon" and is 7-1/2" tall and happens to be the prettiest one of all - they were all issued in 1983 and retired in 1988. I suspect they can only be found in the secondary market as they are not being made anymore, you wouldn't be able to find them in a store where they sell china (you might have to pay a premium price for them as they are retired, therefore rare). You can try searching for them on ebay, you never know if someone is selling one of them. They look beautiful together, but just as lovely by themselves. Good luck in your search! Regards, Maggie
