Issued in 1978 during Ferdinand Marcos's 'New Society' (Bagong Lipunan) period, this note honors Sergio Osmeña, a pre-war Philippine president and statesman who died in 1961. The reverse depicts the Gusaling Batasan (Legislative Building) in Manila, now the National Museum, symbolizing the government institutions of the Republic. This denomination and design series reflects the Central Bank of the Philippines' modernization of the currency system during the late 1970s.
The obverse features a three-quarter portrait of Sergio Osmeña, the second President of the Philippines (1944-1946), rendered in formal business attire with suit and tie, positioned on the left side in classical banknote style. The right side incorporates a large circular security medallion with concentric brain-like or spiral patterns serving as both a security device and design element. The Philippine national coat of arms seal appears in the bottom right corner. The reverse displays a detailed architectural rendering of the Gusaling Batasan (Legislative Building), a neoclassical structure with prominent colonnaded portico and pediment, centered within an ornamental composition. Both sides employ a consistent color palette of pink, red, tan, brown, and yellow with intricate linework backgrounds creating a complex anti-counterfeiting pattern. Denomination numerals '50' and text 'LIMAMPUNG PISO' appear prominently on both sides.

Intaglio (recess) printing combined with multicolor offset lithography. The note was printed by Giesecke & Devrient (G&D), a leading security printer, as indicated in catalog references. The intricate line patterns, security medallion, and detailed portraiture are characteristic of the intaglio process, while the multicolor background was likely applied via offset lithography. No printer imprint appears on the note itself, which is typical for Central Bank of the Philippines notes of this era.
This is cataloged as P-163b, indicating it is variant 'b' of the 50 pesos series (distinguishing it from P-163a and potentially other variants).
