Small vintage silk screen with pop art fish

Vintage screen print, probably from 1980, made by a Danish artist. Cheerful image of 3 fish executed in a pop art style. The signature is unclear to us. The condition is fair, the paper on which the work is made is slightly discolored on the edge, see details. The dimensions of the frame are 31 cm wide and 35.5 cm high, of the work itself: 19.5 cm wide and 22 cm high.
