In order to celebrate the 160th anniversary of International World Fair Day, Google has replaced its official logo on its homepage with a new doodle. The world fair doodle, which is different from previous doodles in the fact that it’s interactive and allows users to scan over it with a magnifying glass, features families celebrating at a fair. They are gathered around stages, booths, a horse-drawn carriage, flags and a giant tree.

The first World Fair Day was held at the Crystal Palace in London’s Hyde Park on May 1, 1851. England’s Prince Albert, the husband of Queen Victoria, primarily organized the first fair, which was modeled after Paris’ tradition of showing national exhibitions, with inventor Henry Cole. The two wanted to showcase their country’s industrial strengths to the world.
