Vintage souvenir cardstock megaphone for the Milwaukee Bucks with Phillips 66 advertising. This item would have been produced between 1968-1972*. It measures about 10.25" tall, and white showing a few creases, it is still in pretty good form! 

*NOTE: By studying period magazine ads, I discovered that Phillips 66 used the slogan "At Phillips 66 it's performance that counts" in COMPANY print advertising between 1955-1972, after which time they changed their slogan to "The Performance Company". The Bucks became an NBA team in 1968, therefore, this megaphone would date between 1968-1972 because of the old Phillips slogan. Interestingly, the megaphone was manufactured by "Sealright", a company who specialized in coated paper products. This company was acquired by Phillips 66 in July 1964 (discovered doing research in Newspapers.com).
