Kilian used a method that combined precise line work with complex ornamental patterns. His letters are constructed using scrolls and human figures. Kilian avoided simple outlines. Instead, Kilian built each character as a three-dimensional object. The "New ABC Booklet" series demonstrates Kilian's ability to balance formal typography with Mannerist decorative trends. Kilian often used the auricular style, which featured fleshy and organic shapes. This style was popular in metalwork and translated well to copperplate engraving.

Modern collectors value these prints for their graphic strength. The monochromatic nature of the engravings makes them suitable for contemporary spaces. Each letter functions as an independent piece of art. These works provide a connection to the history of book design and the development of European typography. They offer a way to display historical art that feels structured and deliberate. The clarity of his engraving ensures that the details remain sharp even in modern reproductions.
