Cards cover the numbers 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 in Czech Sign Language. Each card must include: the number name in English and numeral (e.g. "Eleven (11)"), plus a one-line description in English.

Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no real brand logos, no watermarks Anatomically accurate hand positions. Verify with deaf-community resources.
