On the occasion of the 60th anniversary of the gigantic Seattle Home Show, the Seattle P.I. takes a look back at a few of the revolutionary items that were introduced there in 1939: a completely automatic bread toaster, effective laundry soaps that eliminate the need for boiling, and irons that hold water for steaming out wrinkles. Amongst the marvels of this year’s show are five model homes squeezed under the seats of the Seahawks Exhibition Center with plenty of room left over for 600 exhibitors in the center itself. And these aren’t little doll houses, one measures in at 2800 square feet.
