When the Spanish arrived in Mexico they came across the Aztecs. The Aztecs had a drink which they made from a bean they called CHOCO (bitter).They would put this bean into water (ATL) to produce CHOCO-ATL (bitter water).The TL sound is common in the Aztec language but not in Spanish.The Spaniards inserted an A between the T and L and pronounced the drink CHOCOLATE.The first poster is of some of the girls from Memories Off 2nd.I never actually watched this anime, but I do remember it being popular enough to spawn several titles.
As for the quality of the poster image, I think that it would be considered good even by today’s standards. Angel, Kiddy Grade, and more recently, Mawaru Penguindrum.
