So, in the spirit of asking for information on things while providing very little detail…
I remember dimly from my childhood an exhibition at Denver’s Museum of Natural History. It was full of artist’s representations and speculations of how animals would evolve in the future (mostly, I think, after a nuclear war). I believe this would have been around the mid-1980s.
I know this is skimpy, but does anyone have any ideas what I saw?
Some of the pictures linked are of physical models, not the book’s illustrations, so, unless they’re links to the wrong things (and I haven’t read the book in almost 20 years, so that’s possible), there does seem to have been something of the sort for it. The time period works out, as does the concept (though, IIRC, it doesn’t include an atomic war…just simple passage of time).
