Wollrabe followed the traditions of formal portraiture. Wollrabe avoided the loose brushwork seen in contemporary Impressionist movements. Instead, Wollrabe focused on the clear depiction of status through attire and accessories. His portraits often include specific items like a brooch or spectacles to define the personality of the sitter. The Portret van Jan Heemskerk Azn shows this focus on political dignity. Wollrabe used a neutral palette to ensure the subject remained the primary interest of the composition.

Modern collectors value these prints for their historical accuracy and formal composition. These portraits document the social hierarchy of the Kingdom of the Netherlands and its territories. The portraits of Queen Wilhelmina provide a sense of continuity and tradition. Because the style is restrained and classical, these prints suit traditional interior designs. These prints offer a sense of gravity and historical context to a room without using loud colours or abstract shapes.
