This is a 1926 postage stamp from Costa Rica, featuring the Asilo Chapuí in San José, a historic psychiatric hospital established in the late 19th century. Printed by Waterlow & Sons Ltd., London, the design shows the architectural façade framed by lush tropical palms. The stamp carries a bold black surcharge, altering the original denomination to 5 céntimos. With its intricate engraving and clear overprint, this issue is a fine representation of early 20th-century Costa Rican philately. It remains an attractive collectible for those interested in architectural themes, surcharged issues, and Central American postal history.
