Guy de Gastyne was born in
Neuilly-sur-Seine on 10 May 1888, In the preview of the
1911 Coupe Dewar final between
USA Clichy and , the French
newspaper ''L'Auto
(the future L'Équipe'') stated that Clichy's goalkeeper
Pierre Chayriguès was the second-best in the capital after Gastyne. In the following year, on 14 April, he started in the final of the
1912 Coupe Dewar, helping his side to a 3–1 win over
Club Français. Gastyne made four unofficial appearances for France (
UIAFA), being the goalkeeper of the French squad that participated in the 1911 UIAFA European Football Tournament at Roubaix, an unofficial European Championship organized by UIAFA, in which France was knocked out in the semifinals by
Bohemia (1–4). He is thus the most capped player of UIAFA's France with four appearances, alongside club teammates,
Alphonse Nicol and
Auguste Schalbart, plus
Carlos Bacrot and
Victor Denis. After the
First World War, Gastyne became a talented painter, and remained so until the mid-1920s. He then developed into an
art director, and his first work as such was
Little Lise in 1930. His most notable works were
O Silêncio é de Ouro (1947),
Mataram o Pai Natal (1941), and
Onde Está a Felicidade? (1934). Gastyne died in
Creteil on 3 February 1972, at the age of 83. ==Selected filmography==
