What to do with all those millions of obsolete-once-essential objects of American know-how? Why not have a show. OBSOLETELY FABULOUS is the MFA Design 1st year exhibition curated by Kevin O’Callaghan. See what do do with old phone booths and vintage switchboards; check out the abacus clocks and telecommunications dinning utensils, and more, more, more. Open to the public on Monday April 28 with a FABULOUS reception on Monday May 5.
