Cover From Lithuanian Occupation Of Memel (1923)

I thought I would share this cover with you, which I bought yesterday. It's from Memel, during the Lithanian occupation, and was sent from the Kreisrsabbinat der synagogengemeinde zu Memel (County Rabbinate of the Memel Jewish Community) to Frau Katharina Lazarus in Vienna. Unfortunately, there are no contents.

It has 225m postage (2 x 100m on 25c (SG 4) and 1 x 25m on 5c (SG 2)), cancelled "Memel 23 2 23" with the "* * C canceller" type, and registered sticker. The postal rate is correct: foreign letter rates at that time were 25m per 20g and an additional 25m for registration.

The letter was posted on the day before French troops finally left Memel, following the Lithuanian occupation of 10th January 1923. Oddly, there is no receiving cancel on the reverse, although it does have three nice Memel Rabbinat adhesive seals. If you look up Katharina Lazarus on Google, there is a lady who lived in Vienna and died there in October 1924, aged 82. I wonder if this was the same person as the addressee?

Interesting cover! I'd also be curious as to the sender's fate. If they were still alive in 1939, it's pretty likely they were murdered by the Nazis by 1944.
