Published Books, 1899, 1935

This series consists of two published books. The first book consists of pencil sketches and reproduced autographs of Burgtheater actors published in 1935. Many of the sketches also include actual autographs obtained by Sigel. A list of Burgtheater actors' license plate numbers kept by Sigel (to more easily obtain autographs) and a coupon for one autograph sold by the theatre to autograph seekers are included with the book. The second book is a history of the Burgtheater by Rudolph Lothar published in 1899 as part of the Dichter und Darsteller series.
