Unofficial label.
Cassettes manufactured and sold in Russia, Poland and probally other countries in Central and East Europe.
Cassettes were implemented in various ways. Sometimes the "Max records" logo was on the cover. Other times the cassette cover was copied from the original release (e.g. Club Tools, Koch etc.) and the "Max records" logo was printed only on the tape. Some releases are typically Polish - i.e. they have Polish original covers copied.
