Overview
This is a rare 19th-century trade catalogue from Bullock & Crenshaw, a premier Philadelphia firm specializing in importing and manufacturing scientific and chemical apparatus. The booklet features a stunning marbled paper cover and a pasted-on illustrated label showcasing scientific instruments of the era, including balances and distillation equipment.
Story
In 1849, two Philadelphia druggists teamed up to supply America's rapidly growing university laboratories. This catalog was their golden ticket, offering schools everything from imported German glassware to precision scales. It represents the exact moment science transitioned from a hobby of wealthy gentlemen into a rigorous academic discipline.
Maker / Origin
Bullock & Crenshaw was founded in Philadelphia in 1849 by Charles Bullock and Edmund A. Crenshaw. Located at 528 Arch Street, the firm became one of the most respected names in American chemistry, known for importing high-quality European laboratory equipment and manufacturing their own precision instruments.
Condition & Value
The exterior shows light wear consistent with age, with minor corner bumping on the label. The marbled paper retains vibrant coloration. Excellent preservation of the cover; interior page condition and completeness will ultimately dictate the final value.
