Stamp collectors, this is a really nice find! We're talking about the complete Spain 1962 'Day The Stamp' issue, numbers 1318 through 1320, all in absolutely pristine mint condition. These are unmounted mint/never hinged stamps, which is exactly what serious collectors look for - meaning they've never been attached to an album page with hinges, so the original gum on the back is completely intact and untouched. The condition is what really makes these special for any Spain collection or thematic 'Day The Stamp' collection. Whether you're building a comprehensive Spain collection, focusing on 1960s European stamps, or just appreciate well-preserved philatelic items, this complete set represents that perfect combination of historical significance and excellent preservation. They're ready for your album, display, or to hold as investment-quality pieces that maintain their value over time. For collectors who understand the importance of never-hinged condition and complete sets, this trio offers that satisfying completeness that makes a collection feel truly curated and professional.
