USA: The History of Hockey

On October 20th the US Postal Service and the Canada Post jointly issued a stamp dedicated to one of the most famous sports in North America: Ice Hockey. In the 1800s, the sport truly began to take shape in Eastern Canada. By the late 19th century, the game had grown popular in the United States. American Malcolm Greene Chace became interested in the game and assembled a group of players from various universities. In 1896, a team from Yale, which included Chace, faced Johns Hopkins University in the first college hockey game. The National Hockey Association began play in 1910 and evolved into the National Hockey League in 1917.

I'm happy to receive some covers with this nice stamp with first-day cancellation and even one cover showing a very nice souvenir sheet.

Liechtenstein: The 200th Anniversary of the K.K.Briefsammelstelle Balzers

The history of Liechtenstein’s postal service began 200 years ago with a mail collection station in Balzers. On 1 September 1817, the k.k. österreichische Post (Imperial and Royal Austrian Post) opened a mail collection station in Balzers, followed in 1845 by a second collection station in Vaduz.  By 1912, there were a total of five Austrian-run post offices in Liechtenstein. That same year Liechtenstein also began to issue its own stamps. After the First World War, Liechtenstein left its 100-year relationship with the Austrian post and joined the Swiss PTT, concluding a postal contract with Switzerland in 1920. The move was regarded as necessary requirement to adopting the Swiss franc and customs treaty with Switzerland. In September 2017 the Post of Liechtenstein celebrated this Anniversary with several events and also by issuing this nice sheet you can see on the following cover cancelled by Balzers Post Office.
