I assume this duck was just made to be decorative rather than as a decoy, since its just a domestic duck--though I suppose it could have been used as a sign advertising ducklings--or duck eggs?--for sale! It definitely lived outdoors for a good number of years, with almost all of the white paint gone from one side, and this terrific alligator cracking to the paint on the "good" side. Still firmly attached to its metal post and perfectly ready to stick back in the yard somewhere, though I'd be inclined most inclined to hang it on the wall. 

9 5/8" tall including post; duck itself 6 1/2" tall x 6 1/2" across x 7/8" thick.
