Eerelman, Otto – Het Frederiksplein te Amsterdam tijdens de intocht van koningin Wilhelmina, 5 september 1898, 1898-1900 Rijksmuseum: part 2

The picture has something of this: people, cavalry, group, many, military, festival, man, mammal, crowd, ceremony, seated, army, group together, soldier, war, wear, parade, celebration, skirmish.
Perhaps it’s a painting of a group of men on horses in front of a building with a fountain in the middle of the picture.
