Going counter-clockwise from the left: From the May 1936 issue of American Home magazine. From the October 1945 issue of House & Garden. From the November 1960 issue of House Beautiful (enlarged to show detail). Finally, from the July 1962 issue of Everywoman's/Family Circle.

That first one was originally posted to Flickr on June 11th, 2011. Since then, I've actually acquired some of those pie plates for myself, but I still haven't tried the double-up piecrust trick. I use 'em mostly for roasting vegetables.
