Obwohl bereits am 25.6.1922 geschehen, schreibt The New York Times Nr. 23570 auf S. 92[?] (= S. 2 des 6. Teils) nochmals über die österreichischen Briefmarken [darunter IKO 142]:

"         MUSIC OF FOREIGN LANDS

[...] GERMANY.

     Bayreuth's revival of its festival [... 1924 geplant ... "patrons" können ab 1.9.1922 unterstützen ...].

     Austria's new issue of a series of musical postage stamps continues to interest collectors and musicians as well. These "musical stamps" do not, on delivery of the letter bearing them, play a tune. They are familiar portraits in miniature, though admirable reproductions, of the famous composers whose lives were in large part passed in Vienna. Stamps bearing the picture of Haydn are worth 2.50 Austrian crowns, while a Mozart stamp is worth 5, a Beethoven 7.50, a Schubert 10, a Bruckner 50 [recte 25], a Johann Strauss [recte 50] and Hugo Wolf 100 Austrian crowns each."
