1948 US Chickenstamp

Also a part of the collection I bought. Shows the US chickenstamp from 1948. Issued on september 9th of that year. Do have 3 FDC , all different. Here -in The Netherlands- we have official FDC's from 1950 with all the same picture. The FDC's of this chickenstamp are not. 100 years US Poultry Industry and also the 100th Anniversary from the First Boston Poultry Show. $$$$ are very important as you can see on the enveloppe. Poultry's shows here are not initiated by the industry but breeders who keep the chickens for hobby.
