What started as a souvenir in the 1950s, became a serious collection by the 1970s, a museum by 1982, and is today the world’s largest and finest collection. Museum co-founder Barbara Marshall combined her love for small things with an eye for detail refined throughout her professional career in Hallmark’s art department and volunteer service at The Nelson-Atkins Museum of Art. The combination resulted in a patron that desired only the highest quality work from artists that could meet her standards.

Marshall encouraged artists to create their dream fine-scale works, allowing many artists to explore the boundaries of the art form. The outcomes can be seen throughout T/m’s miniature galleries, including Emperor Charles V of Spain and Queen Isabella of Portugal.
