Autograph Letter Signed ('A. Picard') to Georges Berger (1834-1910), Directeur général de l'Exploitation de l'Exposition de 1889.

8vo: 3 pp. Bifolium. Very good. Written in French. After an 'etude attentive de rapport de M.M. de Lacretelle et Millas et des autres documents en ma possession' on the Exposition's foreign returns he finds 'certaines lacunes et certains points douteux' concerning which he hopes Berger can enlighten him. He gives a list of seventeen officially-participating countries, each with the subsidy it has received in francs, complaining that 'huit de ces chiffres sont douteux'. This is followed by a similar list of six countries which did not participate officially.
