I'm guessing this is from the 1950s, surely no newer than the '60s. Made of wood, painted. It has two bulbs, the bright one at the top, and a night light in the base. The switch changes from the big one, to the small one, then to both, then off.
I believe this is missing a top half of the bulb covering, but makes a fine lamp without it. Found a shade that looks good on it.
I make frequent trips to the Des Moines area and can meet with a buyer at some convenient location for the sale.
