25 Kasutu - Tobacco note

This is a commodity-backed novelty or promotional issue rather than a legal tender banknote — "tobacco notes" of this type were privately circulated instruments, sometimes redeemable against stock held by the issuing company. The dual branding between Port Avastus Bank and Poneet Tobacco Company suggests a cooperative arrangement, though neither entity appears in standard central banking records, which places this firmly outside mainstream monetary issuance.

Polymer substrate on a private or semi-private issue of this scale is unusual and points to a relatively recent production date — polymer security printing has not been economically viable for small-run novelty issues until the last two decades.
