Jiro Kuwata Operation: Mystery! cover, 1969

This is very cool!

I'm a huge fan of Kuwata as well. He's definitely under appreciated. This is a beautiful example of his talent. Congrats on adding it to your amazing collection!

Wow that is a beauty, love the color and the reaction of the woman/ghost.

The blank eyes of the sleepwalking girl combined with the dark red and black background makes me instantly want to pick it up and read the book ... 
Great catch, good choice ! I love Kuwata and especially his use of color

The heavy use of black, the way he uses red to create the mysterious background figure and the cool ghost in the foreground adds up to a very striking cover.

Love this cover, a beautiful example of Kuwata's talent!
