cool. good stuff Timmy the ultramorph. They definitely ended up with a winning design

People can just Google "Ron Cobb Alien Concept" even add ships and it will find these for you.
Its interesting as some of his work was clearly influential in Alien Covenant, from slight similarities with the Lander and some of his work, to the same with the Covenant ship which i had mentioned and shared some of those images in a previous post prior to AC hitting the Box Office... Also the Covenant Bridge is very similar to some of Ron Cobbs Nostromo Bridge concept works.
Lucky they never used Ron Cobbs Alien Monster Concepts though lol

Yes, some Ron Cobb designs and the second image is by Chris Foss. They were first included in The Book of A L I E N by Paul Scanlon and Michael Gross.

I have 2 copies of both editions as that's the kind of geek I am!
I don't find them odd at all. What you have there are some classic late 70's designs!
