ts102 This is a rare and unique vintage postcard from the Belgium Natural History Museum of this unique bird species of the Common Chaffinch (Phylloscopus Collybita). Whilst the card does not state the date this was published in 1940 and the souvenir for visitors of the Musee Royal Histoire Naturelle De Belgique of the era with beautiful full painting of the bird - has very light corner surface impressions from former album storage but is otherwise in truly prestine condition (postally unused too) & specialist wartime souvenir.
