A classic early-20th-century 1 Centavo definitive from Paraguay, featuring the national coat of arms framed by bold line engraving. Issued around 1903–1905, this stamp represents the country’s transition into modern postal design and its integration within the Universal Postal Union (UPU), noted in the lower tablet. The deep blue-green shade and fine detailing make it a desirable example for collectors of Latin American classics. A strong addition to collections focusing on early Paraguay, UPU issues, or coat-of-arms motifs.
