The online vendor writes: "A very hard to find original vintage postcard from the 1920s showing a pair of Kuvasz dogs 'Allein' and 'Wastl' from the Rosenhain Kennels (Asta vom Margarethenhof) in Gauting, Germany. It has been postally used in Germany and is postmarked Munchen (Munich), 1929."
This is from the private collection of Gail Dash, Casablanca Kennel, California. Thank you.
