The team's "pinwheel" logo, originally designed by the cousin of Harry Glickman, Frank Glickman of Boston, it is a graphic interpretation of two five-on-five basketball teams lined up against each other. One side of the pinwheel is red; the other side is silver, formerly black or white. The logo has gone from a vertical alignment to a slanted one starting in the 1991 season, creating a straight edge along the top. The Trailblazers have had 5 different logos over their 45-year history.
2017 - Present
The main change is the swap of the colors in the pinwheel, with red moving up top, and white – instead of silver – going to the bottom. There’s also a slight design change in terms of the angles and the ends of the pinwheel which do look pretty nice.
As for other changes, the font has been updated — there are now serifs on both the “P” and “T” — and the lines are now at a 45 degree angle, which according to the team represents “the 45th Parallel North that leads on a path to the Northwest region.” Anyone who has driven over and over again past that 45th Parallel sign on I-5 in Salem can attest to that.
