Bullseye And Socked On Nose Cancels

A SON from the town with the shortest name in the Netherlands, the village of Ee in northern Friesland province. Wikipedia says the population was 834 in 2017.
Several places around the world with two-letter names. Even shorter than Ee is Ii, Finland. Still looking for one of its cancels!

Nice one EdziuMM!

Here are two commercial postcards of the same company in Werdau,Saxony in eastern Germany. They were clipped from a newspaper or magazine and returned to the company by different respondents from Chemnitz. The cancels on the cards are:

CHEMNITZ
12.09.90

KARL-MARX-STADT
17.10.90

The cards were sent at a time when the DDR regime had collapsed, and unification of the two Germanys was happening quickly. In fact, the "Karl-Marx-Stadt" cancel was applied a week after the official date of unification on October 3, 1990. It shows the use of an out of date and politically incorrect canceller. The Karl-Marx-Stadt name was given to Chemnitz in 1953 under the DDR's Socialist Unity Party rule.

The card with the "Chemnitz" cancel was sent before unification, showing that the change back to the city's traditional name had already occurred.

What has got to be one of the most wistfully intriguing town names is Seldom Come By, Newfoundland.
Alas, it was a weak strike on this stamp and off 90 degrees, but still a SON.
Seldom Come By is a locality on Fogo Island, north of Hamilton Sound, that once was important in the codfish industry. The population is listed as 477, though it didn't say when this figure was current. Nearby was Little Seldom.

BUTTENHAUSEN
12.8.03

My old Altdeutschland Spezial-Katalog by Hans Grobe (5th ed., 1975) lists this "three circle" thimble cancel of Wurttemberg with the 1851-75 stamps.

Several other nice features of the card include a sharp Macon, Ga. receiving cancel and a panoramic view of little Buttenhausen. The sender bought the nice "Gruss Aus"/greetings from picture postcard and then decided he/she had a lot to say.

MARKGROENINGEN
10.7.05

Here is another 1850's "three circle" Wurttemberg cancellation used after 1900. This one is on a domestic postcard to Kochendorf, Wurttemberg. As a bonus, there is a KOCHENDORF 10.7.05 "three circle" receiving cancel, but either the outer rings are clogged with ink, or the device appears to be a bit worn out.

Ever notice my avatar? I couldn't resist a SON from a place named BOOM! It's a town of about 17,000 in Belgium's Antwerp province and it snnually hosts an "electronic dance music" event called Tomorrowland.
My SON searches turned up a BOOM in New South Wales, Australia, too, though I haven't been able to track down its population.

HOLY CATS! I never before noticed that I after the BOOM in the Australia cancel. So I didn't find a BOOM in Australia, too. It's BOOMI.

AAAAARRRRGH! It wasn't me who found that Boomi SON. I copied that pic from some other source!
I QUIT! Tapiocafication of the brain.....

A nice sock from the now-merged villages of Olsberg and Bigge in Germany's North Rhine-Westphalia. The cancel plugged the town as a natural wonders tourist attraction.

An acceptable sock, but a bit of a puzzler. Montreal, Jamaica? Haven't yet been able to find a place in Jamaica named Montreal.
Maybe someone out there knows what or where Montreal, Jamaica is or was....

Montreal, Jamaica was located in St. Mary's Parish. "The Chronicle Postmark History Of The Post Towns Of Jamaica" indicates it first used the modern single ring postmark that you have shown on July 1, 1954. I have no idea if the town still exists or or has a post office.

Totally off-topic but a fellow by the name of Ian Fleming also lived in St. Mary's Parish at a place called Goldeneye and wrote quite a few books while living there.

How about that? Thank you!
BTW, I've read a bunch of books by that Fleming guy.

Here is another form of the Boom, Belgium cancel from my collection:

Linus

A March 31, 1938 Brussells cancel on a Belgium rose-red 1 franc tete-beche pair, Sc, 187a.

MUNGAIRIT
08.12.00

This modern Irish cancel of Mungairit (English = Mungret) is from a rural suburb of Limerick in the southwest of the country. There was once a theological college in the area. It is also the site of a ruined, 12th century Norman style abbey.

According to an online article in the Limerick Post the Mungret post office was one of eight closed in County Limerick in 2018.

From Wikipedia, "Mungret was an early monastic site, founded before AD 551 by Saint Nessan the Deacon."
