I don't get them anymore but I used to pore over the Smithsonian catalog, for clothes & stuff from far away places.
Used to like the lighting catalog from a place in Oregon, Rejuvenation Inc. I finally told them to stop; I had bought a lot of stuff from them in the past since their fixtures made sense with my last house, which I was renovating and keeping it in its old style.
I received a lot of catalogs for years from landscape design source firms. Some of those were ooh lah lah for plants, for wrought iron components, for items like copper mail boxes (I bet those get stolen), plus all the construction material catalogs. Among the most delicious catalogs were the beautifully made terra cotta pots people or granite this and that sellers; the stone yards.. the tile places.. the porphyry pavers..
The only thing I get now is my old university magazine for alums. I still like to look through it, a quick pass.
