100 Baht 'Ploughing Ceremony' Series 2, type I 'Contract'

The Thai royal ploughing ceremony (Raek Na Khwan) depicted on this series dates back centuries as a Brahmin-derived rite performed by the king to ritually inaugurate the rice-planting season — its inclusion on Siamese currency in the 1920s was a deliberate assertion of cultural continuity at a moment when Siam was navigating intense pressure from British and French colonial interests on its borders.

The "Contract" designation within Type I refers to the specific contract period under which De La Rue supplied the notes, a distinction that matters for dating purposes since the Series 2 printing spanned several years with incremental variations in signature combinations. Surviving examples without folds are uncommon; the notes circulated heavily in provincial markets.
