Letiny is situated at an elevation of 470 m in the valley of the creek Podhrázský potok at the western foot of the Jezevčí skála (German: Dachsfelsen) rock formation in the district Plzeň-jih (Pilsen South) in western Bohemia. Letiny has a population of about 700 (2017).

Letin was first mentioned in a written document 1243. At least since 1410 it had an own parish church. The beginning of Letiny as a health resort dates back to at least 1766 when a spring with iron-containing waters was discovered and a former hunting-lodge was converted into the first bath house.

The new  main spa building [left, no. 3382, and below, no. 517] was built in 1901.

The spa closed after 1945 and the spa complex then was used as a convalescence facility for the Škoda factories from Plzeň. Since the 1980s, the facilities are affiliated to the Psychiatric Hospital Dobřany.

The picture on glass no. 4156 [right] shows a view of Villa Anna and Villa Ervin. Villa Anna was built in 1900.

The building depicted on glass no. 4663 [near left] could not be identified.

Comparing it with old postcards from Letiny, the view depicted on glass no. 4664 [near left] could be identified as Villa Zděnka.

Glasses no. 4663 and 4664 [left] are examples of souvenirs where the decoration is based on photographic images. Both of them are signed in the lower right corner: M. Buchar.
