Oblong photo sequence, more substantial than often, consisting of an excellent double-page panorama followed by twenty two pages of photos of prominent Chicago sites. The panorama shows a mixture of sailing and steam ships, the vehicles in the streets are all horse drawn. Covers a little rubbed, otherwise good. Usually the images in the concertina within are detached from one another, but in this example they are still intact. Date not provided: c. 1890. External dimensions approximately 91/2" x 6" (24cm x 15cm).
