On Anthropologie's site, I queried 'owl' and received more results than I could post in a lifetime, among them a number of unrelated bowls and a pair of flats I like much better than the Keds:
(Also, search eBay and you'll find zillions of listings for owl jewelry from the '60s and '70s, when it apparently was at the equivalent level of Topshop/H&M popularity...)
