FD was reading a several-weeks-old New York Times Book Review and saw a mention of a new book on baseball cards. Collecting baseball cards, once nearly universal among young boys and kept up by some as they grew older, is now a dying hobby, it seems.
FD collects lots of things: Books, post cards, cobalt glass (but only very specific items), old cinnabar-like jewelry, pencils, small glass fish made by Lalique, and more… But this may be because FD is older than the internet. FD suspects that when all is available virtually, perhaps not much is needed concretely. And, perhaps collections become virtual, too (FD has a collection of “Astronomy picture of the day” pictures, in her picture folder on-line…).
