Australia International Space Year 1992 Miniature Sheet

This is an Australian miniature sheet (souvenir sheet) issued for International Space Year 1992, featuring three se-tenant stamps. The sheet's upper portion displays a dramatic image of Earth from space with Australia prominently visible, alongside a satellite with gold solar panels against a dark blue background. The three stamps depict: the Helix Nebula (45c), The Pleiades star cluster ($1.05), and Spiral Galaxy NGC 2997 ($1.20), each labeled 'INTERNATIONAL SPACE YEAR 1992' and 'AUSTRALIA'. No postmark or cancellation is visible, suggesting this may be a mint sheet rather than a used FDC.
