Revell has reissued it's kit for the Creature of the Black Lagoon.
This builds into a very good model display, which includes a swamp creature on a rock by it's foot, a base, and some kind of branches. There are seams to deal with, but with some patience, they can be filled easily. I built one of these years ago. While painting it, I used a dark green base, and dry brushed a gold color paint over it to accent the highlights. I think it worked out well. The original movie was in black and white, so the correct color is pretty much up to you and your imagination. The production staff probably used colors on the suit to look good on camera, rather than actually worrying about what might look realistic in normal color daylight.
This figure kit adds a great addition to your Universal Pictures monsters collection.
There are actually two actors who played the creature, one being Ricou Browning, who did the underwater work. I met him years ago, he's a nice fellow, and always eager to talk about his work.
