As I was on holiday in the Reich during these days, and not in Karlovy Vary, I can unfortunately add nothing to the time the overprints were done and what preceded it. I had to extend my holiday involuntarily at that time because the borders were closed. The borders between the Reich and the Sudetenland did not reopen until 4 October 1938. At that time, I was staying in Leipzig and immediately after the opening I went back to Karlovy Vary. On 4 October 1938, I arrived in Cheb by train, because the railway to Karlovy Vary was not yet in operation, I had to travel back by car.
On the morning of October 4, 1938, the Führer visited Karlovy Vary. That very afternoon I went to the main post office. Although I came during office hours, the main door was locked. A large number of people were crowded inside and outside. After some 15-20 minutes I was let in and had to join a long queue. At first, I had no idea that these people also wanted to buy Karlovy Vary provisionals. I thought that on the occasion of the Führer’s arrival, a special postmark was being applied, or that some commemorative sheet had been issued. But what a joy I was and was pleasantly surprised to see the new overprints. Everyone got only a few stamps (6-10 pieces) of lower values. All the higher values, I was told by the postal clerk who sold them, had already been sold out by the morning.
When I came back a second time, I only got 4 pieces. After that, they closed the counter, because the office hours were over. On the next days, 5 October and 6 October, the stamps were sold only in 2 pieces. Later I exchanged a few more pieces (Detem, Fügner) with a collector I knew for some valuable Austrian stamps. As I later found out, the leftover stock of Czech stamps was collected from all 5 Karlovy Vary post offices and transported to the main post office to be officially overprinted with a rubber stamp.
In Karlovy Vary only, these overprints were valid from 4 October to 6 October 1938, while it was possible to use Czech or Reich stamps. From 7 October 1938 until 15 October 1938, these provisional stamps were tolerated and still franked (although they had no postal validity).
I personally sent a registered letter from Karlovy Vary on October 13, 1938 and affixed on it 2 overprints of 3,50 crowns and 50 hellers and 2 pieces of 1 Pf stamps = 0,40 RM. The exchange rate was then 1:10 (4 crowns were 0,4 Reichsmarks). But I had to add one 40 Pf stamp to it. The Karlovy Vary overprints were stamped for me.
It was different in the other towns of the district, where chaos reigned a bit. The postal clerks, mostly retired Sudeten women, had not yet received the new guidelines and were using the old Czech ones. Each district town had a slightly different postal validity.
