Help With Stockholm Sculpture's Name?

Anyone out there good with the names of Stockholm sculpture? I'm trying to label old travel photos/be more accurate with names of things photographed. I have three old pictures of a Stockholm sculpture but am having no luck at all on the Internet finding its name (though I do find its image; always with unrelated text). It looks to me like a Henry Moore version of an ear & is located on the water; on the western edge of Riddarholmen; Västerbron & Stadhuset can be seen behind it. Tack så mycket!
