Spanish Revenue Stamp - 8a Clase (1.50 Pesetas)

This is a vintage Spanish fiscal or revenue stamp, specifically an '8a CLASE' document stamp with a face value of 1'50 Pesetas. The stamp features a central monochromatic blue-gray engraving on cream-colored paper. The allegorical illustration depicts a seated female figure, representing Justice or Law, holding a quill and the 'CODIGO CIVIL' (Civil Code). At her feet lies a bundle of fasces and a Spanish coat of arms featuring the eagle of Saint John, characteristic of the Franco era (circa 1939-1975). The stamp includes a unique printed serial number 'G0178994' at the bottom. It measures approximately 25mm x 40mm with standard line perforations. The condition appears relatively good for its age, showing slight toning of the paper and minor blunting of the upper right perforation corner. There is no visible cancellation mark, suggesting it may be in mint or unused condition. The fine line-engraved details demonstrate high-quality security printing common for government-issued fiscal documents of the mid-20th century.
