Seafair float (probably not specifically a Seattle City Light float, despite title on Flickr) in Grand Floral Parade, Portland, Oregon, U.S., 1959. The same float was featured that year in Seattle's Seafair Parade, but without the roses. "Queen Dian[e]" is Diane Gray. And the man standing to the right on the float is a Rosarian, from the Portland Grand Floral Parade. This is near what is now Tom McCall waterfront park.
