Original costume designs, 391 drawings total, for Carnival parades and balls. 285 of the designs were executed by Léda Plauché or by unidentified artists; 106 of the designs were executed by Bror Anders Wikstrom.

The designs range in size from approximately 7 ½" x 9 ½" to 15" x 20 ½" on heavy drawing paper, in watercolor, ink, and pencil. Several of the drawings have been matted; several of the Plauche designs were cut out "paper doll fashion."

The costume designs are arranged by numbers assigned by the arranger. There are two series: designs by Plauché and designs by Wikstrom. Several dozen of the designs attributed to Plauche are probably not her work but drawings in her possession actually executed by unidentified Carnival artists. Nine oversized drawings were not scanned and are not listed in the inventory.

The krewes for which the costume designs were created are, for the most part, unidentified. Further research will be necessary in order to determine the drawings' dates and the Carnival krewes which commissioned them and to identify positively the creators of some of the drawings currently attributed to Plauché.
