zunächst mit sSe3 abgedruckt, Korrektur 11.06.1943: "Im Problem No. 6 ist uns leider ein Fehler unterlaufen. Auf E3 steht nicht ein schwarzer Springer, sondern ein schwarzer Bauer. Wir bitten um Entschuldigung."
Das dürfte immer noch fehlerhaft sein (mit sBe3 geht einzügig 1. Tf4#!), mit sLe3 aber korrekt.

vollständiger Widmungstext: "Geschenkt von Otto Oppeneimer zur Geburt unserer Schachecke."
