Joseph Fraunhofer, printer's sample for the World's Inventors souvenir album (A25) for Allen & Ginter Cigarettes 1888

This is a chromolithograph print of Joseph Fraunhofer, a German physicist, from the *World's Inventors* souvenir album (A25) created by Allen & Ginter in 1888. The album was part of a popular series of trading cards distributed with Allen & Ginter cigarettes. The print features a detailed portrait of Fraunhofer, known for his groundbreaking work in optics, particularly his discovery of dark lines in the solar spectrum. This is a prime example of the *trade card* genre, which was popular in the 19th century as a marketing tool to promote products like cigarettes.
