Originally uploaded by dieselboi.

ok, i guess the first clue was too easy. the first guess came in correct after less than an hour. i want to make this more difficult.
here’s the next clue. take a guess in the comments. there will be prizes.

UPDATE:

yes indeedy, Padgett got it right and the comment put up is from the portland parks and details the history of this sculpture. Padgett also gets a gift card/certificate for coffee. the faces are of a family and the statue is in chapman park. “the promised land” by manuel. Dedicated on the 150yr anniversary of oregon trail – 1843-1993.
