This image captures a three-tiered glass display case in a museum or exhibition, located in Belchin, Bulgaria. The display showcases historical educational and office artifacts. **Top Shelf:** From left to right, a brass school bell with a wooden handle is displayed next to a large black quill pen. Adjacent to it, a smaller black quill rests within a dark inkwell. A white label identifies these as "School bell" and "Inkwell." Further to the right, an open antique Cyrillic alphabet primer, "Букваръ за първоначални училища отъ Н. В. Вапцаровъ, Пловдивъ, 1891 г." (Primer for primary schools by N.V. Vaptsarov, Plovdiv, 1891), displays various letters. A rectangular, dark wooden writing board, likely a slate, is positioned on the far right, labeled as "A writing board." **Middle Shelf:** Two black photo albums are open. The left album displays two black and white historical photographs of a large, multi-story building with numerous individuals gathered in front, identified as "The school building at the end of the 19th century." A dark green album titled "УЧИЛИЩЕНЪ АЛБУМЪ" (School Album) is partially visible to the right. Several loose black and white photographs are arranged around and within this album, depicting groups of students and teachers, and other historical scenes, including one with uniformed individuals. **Bottom Shelf:** Various books and office equipment are presented. An open book lies on the far left. A dark mechanical calculating machine (arithmometer) from the 19th century is centrally placed. Next to it are several stacked books, including "ИВАНЪ ВАЗОВЪ СЪЧИНЕНИЯ IX" (Ivan Vazov Works IX), identified as by "a Bulgarian writer (1850-1921)." A red, ocarina-like wind instrument is positioned among more open books. One open book displays the title "ХРИСТО СМИРНЕНСКИ" (Hristo Smirnenski), attributed to "Hr. Smirnenski (1898-1923)." A vintage black typewriter from the early 20th century is on the right. Additional stacked books, including "КНИГА ЗА ЦАРЕТЬ" (Book for Tsars/Kings) and "ЧИТАНКА" (Reader/Anthology), complete the display. The entire setup is illuminated by overhead strip lighting and an additional ceiling light fixture, all enclosed within the clear glass case against a light yellow background wall.
