I remember from the sixties a series of cartoon serials based on fairytales. They might have been european. They were 15 to 20 minutes long and each run everyday for weeks. One series was based on the Tinder Box (you know the one with the three dogs: one with eyes as big as tea cup saucers; one, as big as dinner plates; the largest, as big as serving platters), another on Ali Baba, Alladin, and my favorite on the Swan Princess. 
Does anyone know if they can be found on DVD?
