DETROIT (AP) -- The Butzel Long law firm is sponsoring a competition to design a weather vane for the Belle Isle Aquarium cupola.
The winning design will fetch a $500 prize. The deadline for entries is midnight on Aug. 29.
Submissions will be reviewed by a five-person jury.
The competition is open to U.S. citizens age 18 and older. Only one entry is allowed per person.
There are size and other guidelines. Weather vane entries must function and rotate with the wind, be made of non-corrosive metal and reflect the aquarium's historic character. Construction of the proposed design cannot exceed $7,500.
Butzel Long chair Richard E. Rassel says the firm has long ties to the aquarium and calls it a "hidden gem."
