"Yes, a Valladao-Belen with a Bishop promotion, and the first to ever appear before the public !"

http://www.berlinthema.de/Auswahl_PH.pdf-"P.H.s (H48c) löste eine verstärkte Suche nach einer Darstellung mit der nun einzig noch feh- lenden Läuferumwandlung aus, und formell ist die (H48e) die Erstdarstellung. Allerdings sehen wir hier dieselbe gravierende thematische Schwäche wie in der (H48b), daß der Doppelschritt vor dem e.p.-Schlag nicht exklusiv ist und Schwarz ebenso den Einzelschritt spielen könnte – wodurch es zum gleichen Spiel kommt nur ohne den thematisch unabdingba- ren e.p.-Schlag."

http://matplus.net/start.php?px=1600576227&app=forum&act=posts&fid=xshown&tid=2367-"****...and the solution now is complete. Yes, You knew already, I'm sure: "habemus episcopus" - after Q, N and R, a promotion to Bishop in a published Valladao-Belen!"
