The image displays a timeline exhibit on a white wall, detailing modes of transport and carrying methods from prehistoric times to the present. The title, "Преди, по време на и след самара" (Before, during and after the pack saddle), is prominently featured in large grey lettering at the top. Below the title, the timeline itself is depicted as a horizontal line with various illustrations representing different eras and methods of carrying goods. Starting from the left, the earliest depiction is of a human figure carrying a bundle on a stick over its shoulder, labeled with "7000 г. пр.н.е." (7000 BC). Moving right, the timeline shows a horse with a saddle, followed by a donkey, and then a camel carrying a large load, with a cart pulled by animals. These are further segmented by dates such as "6000 г. пр.н.е.", "3500 г. пр.н.е.", "3000 г. пр.н.е.", and "2000 г. пр.н.е." (2nd millennium BC). Further along the timeline, illustrations depict a steam train, a truck with a package, and a person carrying a backpack. These are associated with dates like "1000 г. пр.н.е.", "0", "1000", "1800", and "2023". Each illustration is accompanied by brief descriptions in Bulgarian and English, explaining the role of humans, horses, donkeys, camels, caravans, and eventually mechanical transport in carrying loads. The exhibit is located within the "House of Humor and Satire" in Gabrovo, Bulgaria, as evidenced by the style of the exhibit, which aligns with the museum's focus on humor and cultural heritage. The overall environment appears to be an indoor exhibition space with a clean, modern aesthetic. The lighting is diffused, highlighting the display against a textured white wall. The image is a photographic capture of this exhibit, taken from a slightly elevated, frontal perspective.
