I got this set from Rolland, and the original listing is here.
This is a set of cards edited by Artbox USA, dedicated to the successful The Powerpuff Girls series broadcasted by Cartoon Network.
It’s a very rare collection that appeared only in the USA, and is one of the few licensed collection dedicated to the series. Like all the collections published in the USA, the cards did not benefit from an official album, but a custom made album with dedicated covers was created. The complete set consists of 71 cards + 1 checklist card, all in mint condition, and they presented scenes from episodes and the main characters.
