Full set of decoration, bow, smaller and full size sash, case of issue, statues and award document to a Lady of Honor of the Bavarian Order of Theresa. This particular set was awarded on March 18, 1929, to the Graefin Ludmilla to Castell-Castell. 

The cross itself was made by Eduard Quellhorst in Munich and represents an older, probably returned cross from the 19th century. The Cross is marked as such: “EQ”

The Order was established on December 12, 1827, by Queen Therese of Bavaria, wife of King Ludwig I of Bavaria. She created an endowment to provide an annual pension to twelve unmarried noblewomen: six received 300 guilders each, while the remaining six received 100 guilders each. The pension ended if a member married, but if the marriage was deemed appropriate for her rank, she could retain the order's insignia and be referred to as an Ehrendame (Lady of Honour).

The rank of Ehrendame was also held by various other women, including all the princesses of the House of Wittelsbach. Bavarian women paid a reception fee of 55 guilders, while foreign women paid 220 guilders.

The order's insignia, worn on the left breast, features a blue-enameled Maltese cross with a broad white border, topped with a gold royal crown. The cross's four arms are adorned with blue-and-white Bavarian lozenges. At the center of the cross is a white circular medallion bordered in gold, bearing the letter "T." On the reverse side of the medallion are the year 1827 and the order's motto, “Unser Erdenleben sey Glaube an das Ewige” (Our life on Earth may be Faith in Eternity).

The ribbon of the order is white with two sky-blue stripes along the edges, with the inner stripe being narrower than the outer. The sash is a similarly colored broad ribbon worn diagonally from the right shoulder to the left hip.
