Good morning @qwerrie
Always a happy moment to get some new stamp asquisitions 😃
Queen Willhelmina stamps are indeed very appealing, my favourites from this batch. I hope you get one day the third stamp from the German series, and replace the damaged one. Or, isn't it actually good in this way? Unique stamp through its imperfection? 😉
Maybe I will do that, maybe not.
Frankly: I am not that true collectioneer and dont consider filling in all the stamps in a certain serie. Some even hunt after all versions, color alterations, imprintings, collect both cancelled and uncancelled editions, etc etc etc - you name it. I am not so hardcore type, I collect examples of design that is attractive to me, and easily can skip those I already have (in other color design) or those that are high nominal and thus more expensive
Have a great day, and Hive !PIZZA
