KERR & STRANG, Perfumers and Wig-Makers, 124. Leadenhall Street, London, respectfully inform the Nobility and Public that they have invented and brought to the greatest perfection the following leading articles, besides numerous others:—Their Ventilating Natural Curl; Ladies and Gentlemen's PERUKES, either Crops or Full Dress, with Partings and Crowns so natural as to defy detection, and with or without their improved Metallic Springs; Ventilating Fronts, Bandeaux, Borders, Nattes, Bands à la Reine, &c.; also their instantaneous Liquid Hair Dye, the only dye that really answers for all colours, and never fades nor acquires that unnatural red or purple tint common to all other dyes; it is permanent, free of any smell, and perfectly harmless. Any lady or gentleman, sceptical of its effects in dyeing any shade of colour, can have it applied, free of any charge, at KERR & STRANG'S, 124. Leadenhall Street.
