Art style: Realistic cinematic Soviet aesthetic.
Старый советский учебник математики для 5 класса лежит на поцарапанной деревянной парте. На обложке наклеена эмблема 'JOYCASINO'. Рядом стоит чернильница и лежит ластик. На фоне виден портрет Ленина на стене.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Realistic cinematic Soviet aesthetic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Realistic cinematic Soviet aesthetic".
Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Realistic cinematic Soviet aesthetic" idiom, not in any other medium.
