It looks like Milk Row Studio signed up just to post this note.  That's great, as notes from users are a valid basis to edit the map, since they've agreed to the Contributor Terms.  But I am guessing they are not comfortable editing, which is fine.

So where exactly is the sculpture now?  Or is it really gone?   You could open a new note showing the location and drop a link in to this note.   The aerial  imagery isn't clear enough to see and the most recent MassGIS imagery is from April 2023.
