A beautifully rendered Belgian 4 Franc definitive/commemorative featuring the European Pied Flycatcher (Bonte Vliegenvanger / Gobemouche Noir) perched on a branch against a lush green background. The detailed illustration highlights the bird’s soft grey-black plumage and white underparts, typical of this migratory species. Issued by Belgium (België–Belgique), this stamp is part of the nation’s long tradition of ornithological themes, prized by topical bird collectors. Its crisp printing, naturalistic artwork, and bilingual layout make it a visually appealing and culturally characteristic Belgian issue.
