antique cast metal bronze bears statues, bear figurines bookends early souvenir of Yellowstone

Pair of vintage cast metal bear book ends, 5 1/2" tall. Not weighted, these are hollow inside. One bear is missing the original felted paper bottom.

These are marked Yellowstone Park, rather than Yellowstone National Park as most of Yellowstone's souvenirs were during much of the 20th century. I'm guessing these are probably early 1900s vintage, actual antiques.

They are not actual bronzes however, but a bronze finish on cast spelter metal. Very nicely detailed, lovely old pieces.
