I first took this for a rhinoceros, but now I am wondering if it might not be a Styracosaurus or some other one horned dinosaur? Rhinos do look a lot like dinos, so I think one can call it whatever one likes, and certainly it's blue paint facilitates make believe! I really love the smiling face and yellow horn combination, and how it appears as if creeping along stealthily despite its voluminous rear! Pure delight.
7 1/8" l x 4 1/2" t x 1/2" thick and in good shape. It clearly once stood on a base, now lost, but it stands up steady on its own just as it is. 1920s-40s I would think.
