Brosse à dents — Brevet américain n° 758 109. Cette œuvre est l'illustration originale de l'Office américain des brevets pour une brosse à dents, présentée comme une gravure nette à l'encre noire avec des vues légendées du manche et de la disposition des poils. Le dessin se concentre sur la forme structurelle et les détails fonctionnels plutôt que sur la décoration, mettant l'accent sur la prise en main, la forme de la tête et le placement des poils destinés à une hygiène bucco-dentaire efficace. Médium : gravure technique officielle de brevet, caractéristique des conceptions d'utilité domestique du début du XXe siècle.

H. E. Sandiford était un inventeur américain associé aux améliorations pratiques des ménages à une époque où les outils de soins personnels se normalisaient. Son brevet reflète l'intérêt de l'époque pour l'ergonomie et la santé quotidienne, documentant des raffinements progressifs des objets courants.
