STRONG & OLIVER. CARPENTERS AT WORK. c1920 Glass plate negative, most likely a dry glass plate image. Dry glass plates came ready made. The photographer need only remove the paper cover, expose the plate and develope the image. This set of two glass plate negatives are the only ones in my collection. At least the only ones that showcase trades. The toolchest is labeled 'Strong & Oliver'. Displayed on the toolchest is what looks like a Stanley #45 plane, some saws, a transitional plane and a brace.
