Every time we go to the P-I photo archive, we spend at least a few minutes perusing photos and turning to their backs to see when they were taken.
That curiosity — and the often-surprising results — has turned into a weekly gallery in which we share some of our favorite finds and give you the chance to guess the decade.
This week’s gallery includes Mercer Island’s most famous swimmer, a bootleg bust, KIRO radio’s Maury Island transmitter and “Sweet” Lou Pinella’s arrival in Seattle.
