Back when everything was under one umbrella of entertainment and science-- zoo/amusement park/circus/aquarium/stage show/

That is the zoo behind this gentleman. Interesting architecture, much as the Berlin Zoo had at their facility. It looks like a whale skull on his left.

Woodward's Gardens was one of the great amusement parks and is considered one of the "Lost Landmarks of San Francisco", where the public was treated to a wide variety of spectacular attractions and cultural treasures assembled by and staged by Robert Woodward, who had gone on a lengthy buying trip to Europe in the 19th Century, returning with many interesting works of art, which were also put on view for the publics enjoyment. The Zoological Gardens quickly established itself as one of the foremost attractions to visit in California, and upon Ex-President Ulysses S. Grant's return from his Ambassadorial duties in Japan, he made a point of stopping there as part of his travels. Among the many interesting acts and wonders on view at the Gardens over the years was "Chang, the Eight Foot Tall Giant from China", "The Buislay Family of Trapeze Artists and Gymnasts", from France, with one of their members, Gus Buisley, participating in a daring Balloon Ascent from the Gardens, "The Warm Springs Indians", fresh from their victory in the Modoc Wars, who put on exhibitions featuring their "Tribal Dances", "Walter Morosco's Russian Royal Circus", and acts featuring "Trained Bears", all of these attractions in addition to the elaborate Fresh and Salt Water Aquariums on view alongside what was known as the most complete Zoo on the West Coast, courtesy of the imagination and creativity of Robert Woodward, who became known as "The Barnum of the West". The Zoo and Gardens were finally closed in 1894.
