But I discovered, in researching further, really wanting precise reference, that one of the original lead birds had been sold at Christie's in 1994, and so I contacted an antiquarian bookseller who had the original Christie's catalogue, and in it I found this magnificent picture, which included a size reference.
No, otkrio sam dalje istražujući u potrazi sa boljim referencama, da je jednu od originalnih olovnih ptica prodao Christie's 1994. Kontaktirao sam antikvarijat koji je imao originalni katalog Christie'sa i u njemu našao ovu sjajnu fotografiju zajedno s mjerama.
