Collection of British Machin Definitive Postage Stamps

This item is a collection of British Machin definitive postage stamps, mounted on a page of graph paper within a ring binder. The Machin series, first introduced in June 1967, features the iconic sculpted profile of Queen Elizabeth II by Arnold Machin. The collection includes approximately thirty individual stamps in various monochromatic colors such as magenta, blue, olive, violet, brown, and ochre, representing different denominations. Each stamp measures roughly 21mm by 24mm and is printed on phosphor-sensitized paper with characteristic perforations along all four edges. The stamps are organized chronologically or by denomination, evidenced by handwritten annotations on the grid paper. Many specimens show evidence of light cancellation marks, indicating they are postally used. Condition varies across the collection; some stamps appear well-centered with intact perforations, while others exhibit minor corner rounding or slight misalignment. The presentation on hand-annotated graph paper suggests the work of a private hobbyist collector. Notable is a central stamp with a clear 'REPRODUCED' or similar black overprint, which may indicate a specific variety or specimen. The craftsmanship of the stamps themselves represents high-quality photogravure or lithographic printing processes used by Royal Mail printers like Harrison & Sons.
