Hello everyone. 
I just got these stamps in today w/post markings. Anyway someone can identify the postmarks? Maybe they have away of telling where the letter was from?  Google isn’t helping much.
 

I appreciate it as always!

I can´t read all but these are easy to ID: Prag (Prague), München (Munich), Halberstadt, Königsberg, Moresnet (Belgium)

on a few it says Tag der Briefmarke = Day of the postage stamp.

Appreciate it

I started out as a stamp collector when I was a kid.  I paired down my postal stuff to just Polizei related stamps but you can just pick a subject and make a nice collection out of specific stamps and postal markings.

 

Here are a few Police postals.

 

 

Sarge,

 

These are great items. I used to find post cards and covers at stamp and coin shows and they were relatively inexpensive. For someone on a limited budget, stamp collecting is quite fun and won't break the bank.

 

Best regards, stay safe

This posting got me thinking about other postal stamps and postmarks.  Here are a few more postcards with Polizei cancellations.
