In the mid-19th century, the business of trade caravans blossomed in the Užice and Zlatibor area. Merchant heading the caravan was called "kiridžija" (plural "kiridžije"). The caravans had 15 to 20 horses and Zlatibor merchants became famous for their work. Photographer Ilija Lazić took a photo of "kiridžija" Todor Udovičić Gajević (by some sources Todor Gajović) in the early 20th century, which became iconic. Lazić named it "Zlatibor's fast train" and used it for postcards. Real railroad reached Užice in 1912, and number of caravan merchants began to dwindle. With introduction of motor vehicles, "kiridžije" disappeared by 1950. Based on the photo, Miladin Lekić, self-taught sculptor, carved wooden sculptures of Gajević (generically referred to as "Era", name for the inhabitant of southwest Serbia) and his horse, and tall, respectively. They were made of wood from Stubla: Gajević from oak, and horse from elm wood. The sculptures were placed in the center of King's Square in 2013, marking 120 years of organized tourism in Zlatibor. During the 2020 reconstruction, the sculptures were moved to the starting section of the promenade. The sculptural group is called "Zlatibor's fast train", after the photo.
