Brosamer worked during the German Renaissance. He produced many portraits and woodcuts for book illustrations. He is often grouped with the Little Masters because of his skill in creating small, detailed engravings. His style reflects patterns found in the work of Lucas Cranach the Elder, especially in his formal portraiture. He contributed woodcuts to the Luther Bible and various scientific texts. His engravings often depicted classical myths or moral allegories. He also produced a series of woodcuts for a well-known book on the art of proportions.

Modern collectors value Brosamer for his technical precision and the historical detail in his portraits. His woodcuts provide a clear view of the clothing and social status of the sixteenth century. The compact size of his engravings makes them ideal for smaller wall spaces in modern homes. These prints offer a link to the intellectual atmosphere of the Reformation. His images of scholars and nobles are appreciated for their directness and balanced compositions. They represent a sophisticated era of northern European printmaking.
