Contains almost 6,000 views of Europe and the Middle East and 500 views of North America. Published primarily from the 1890s to 1910s, these prints were created by the Photoglob Company in Zürich, Switzerland, and the Detroit Publishing Company in Michigan. The richly colored images look like photographs but are actually ink-based photolithographs, usually 6.5 x 9 inches.
Like postcards, the photochroms feature subjects that appeal to travelers, including landscapes, architecture, street scenes, and daily life and culture. The prints were sold as souvenirs and often collected in albums or framed for display.
