Cruz Delgado (born in 1929) is a Spanish animator who founded his eponymous production company in 1964 and had quite an active career between 1969 and 1990, both on theatrical animated films and TV series.
Logo: On an animated space background with stars moving in and out and some multicoloured nebulas we see the words "cruz delgado" in some kind of weird, yellow font with a very 60s feel. Underneath of them, on the right, a white, handwritten font reads "presenta".
Technique: The stars moving, traditional cel animation.
Music/Sounds: None, it's a silent logo.
Availability: Scarce; this logo (obviously, restored) is used on the very few DVD prints of films by Cruz Delgado.
2nd Logo (1978-1988?)
Logo: On a still space background, colored in two shades of purple, we see the words "cruz delgado" in the same font as before, though slightly remade to look fancier. This time, the word "presenta" is in the middle of the screen with a fancier font than the 1st logo as well.
Technique: None, it's a still logo.
Music/Sounds: None or the opening theme of the movie.
Availability: Extinct; apparently can only be seen on some trailers.
