I found the article and it is just the same story about Detroit Bikes making a Schwinn Collegiate in Detroit. The Manta Ray image is just one that the paper snagged from their archive. It is credited as "A 1971 Schwinn Manta-Ray bicycle on display in the "Keep Moving: Designing Chicago's Bicycle Culture" exhibit Wednesday, Oct. 31, 2018, at Expo 72 in Chicago.
