Interesting.
That's more than half the number of pages in The Last Whole Earth Catalog, #1160, published June 1971.
That edition of the LWHC cost $5, compared to $0.35 for the Popular Science of seven years prior.
Popular Science was printed in a smaller format, it must be admitted.
If you want lots of pages you could buy Vogue or Elle or even Cosmo.
I bought that.
