I am so sorry not to be very good at all at posting photos, but I will try my best in the next future. In the fisrt tome of Felix Youssoupoff memoirs " Avant l'exil " translated " Lost Splendour " one can see the photo of Felix and Gugusse posing for Seroff in 1904 between page 44 and 45 of the 1996 edition published by The Folio Society of London, translated from the french by Ann Green and Nicolas Katkoff ( I have at the moment the book under my eyes, the book has a lovely purple front page, lined in silk, with a photo of Felix in his traditionnal russian boyard costume ). On the reverse of the page with the photo of Felix and Gugusse posing, one finds a 1901 photo of Felix, his parents and his brother and 2 dogs including Gugusse sitting just in front of Princess Zenaide Youssoupoff, Gugusse having his ears " falling down " and not straight ( or bat ears ) as to-day french bulldogs must have according to the breed's standart.
