3D lenticular Space Postcard

I used to often look at Modern Fred's Flickr stream years ago. Just found him on Pinterest and as usual he's got some great images.

I love this lenticular card. Would you say those are GI Joe's? Is the spacecraft a model kit?

There are more postcards to see. I'm not signed up for full Pinterest but you might be.
