This is a souvenir straw hat that was sold at Expo 67, Montreal’s World Fair, held in 1967.  The hat is a standard wide brimmed hat except for the Expo 67 sticker applied to the top of the crown.  It is sized as a 7, but should easily fit a 7 1/8 sized head - it measures 22 3/8” around the sweat band and 6 5/8” by 8” across the opening.  The brim measures 3 1/2” in width at the front and the crown measures 4 5/8” in height.  The hat is a little out of shape and has one blackish mark to the left back of the crown, very minor, and probably would come out with a cleaning.  There is no cracking to the straw, and the quality is much nicer than what one would normally buy today.  Despite its condition, this is a collectible hat - not a lot of these would have survived from 1967!
