20 Dinara Risnjak, OOUR Lavica; Samobor

The "OOUR" designation places this note squarely within Yugoslavia's experiment with self-management socialism — Osnovna Organizacija Udruženog Rada, the basic organization of associated labor, was the legally recognized economic unit under the 1974 constitution. These workplace-issued notes, sometimes called "bonovi," functioned as internal scrip, circulating among workers and accepted at enterprise canteens, shops, and cooperating local businesses rather than through the national banking system.

Samobor, a small town west of Zagreb, had a sufficiently developed local manufacturing base to support this kind of parallel exchange. The "Lavica" enterprise name suggests a specific production unit operating under the broader OOUR framework. Yugoslav bonovi of this type were never catalogued systematically during their period of use, which makes attribution and dating genuinely difficult.
