An authentic documentary-style photograph capturing piles of sacrificial animal hides stacked inside Cairo’s traditional tanneries after Eid al-Adha. The hides appear in multiple colors, including blue, red, and natural beige tones, forming large textured layers inside the industrial tannery environment. In the background, tannery workers can be seen sorting, carrying, and organizing the collected hides after the Eid slaughter season, preparing them for the next stages of leather tanning and processing. The image reflects one of Egypt’s oldest traditional industries, where animal skins are cleaned, salted, dyed, and transformed into handmade leather products through techniques passed across generations. The raw textures, crowded atmosphere, and movement of workers preserve the authentic spirit of Cairo’s “Madaabegh” and the heritage of Egyptian leather craftsmanship. Keywords include Cairo tanneries, sacrificial hides, Eid al-Adha, leather processing, traditional tanning industry, “Madaabegh,” tannery workers, and Egyptian industrial heritage.
