While I remember where it came from, here's another image found in that Jan. 1961 Popular Science story starring William O'Sullivan Jr, who headed Project Echo and the whole satelloon paradigm at the fledgling NASA.
When you see a couple of guys at a 50' table, assembling, folding, and gluing Echo I's Mylar gores using not much more than a pile of footlong clothespins, you can understand why I still hold out hope of replicating one for exhibition as an art object. [On earth first, of course. Baby steps.]
