Jokes with stamps (part 2)

Halved stamps that were officially permitted to be used as such are well known. However, unofficially halved stamps used to meet a specific rate are considered 'damaged' and do not count towards the rate amount. The rate for a letter up to 20 grams was 70 cents from April 1, 1982, to June 1, 1986. The 65-cent stamp was issued on December 15, 1981, so it had to be franked with 5 cents on April 6, 1983. Did the sender from Amsterdam not have any 5-cent stamps at home? He certainly did have 10-cent ones, and resolutely he grabbed the scissors, cut a 10-cent Crouwel stamp diagonally in half, and pasted it next to the 65-cent stamp. Or was there intent involved here? For the halved stamp was affixed first, which is naturally not the usual method. And then there is the addressee, a very well-known philatelist. A 'nice' piece of 'craftsmanship' that was apparently accepted by the Post Office. I have not yet been able to find another piece of mail on which this halving with a Crouwel stamp occurs in that manner. Have you? Or do you perhaps have other examples? Let me know.
