Cancellations

Today part two of my new collecection. Two nice cancellations as you can see. 15-10-1960 at utrecht The European Poultry Conference. Where did they talk about then?? Maybe its to google... The French Revolution cellebration also was good enough to have a nice stamp. The cancellation is from a contest for cocks. Which cock could crow the best, or the most in a limited time. We won't know the result. Still very nice items.
