I don't have a catalogue with L but, in looking for your Canadian stamps, I stumbled on Central Lithuania, and there they were. The first two are from 1920 SC# 1 (red 25f) and #6 (2m orange). The other is a postage due stamp SC#J1 50f violet red 1920-21. Very nice. I like the crude printing. Interestingly, these are worth more used than unused.
Scott has an interesting history of the area.
"At one time Central Lithuania was a grand duchy of Lithuania but at the end of the 18th Century it fell under Russian rule. After WWI Lithuania regained her sovereignty but certain areas were occupied by Pland. During th Russo-Polish war this territory was seized by Lithuania whose claim was promptly recognized by the Soviet government. Under the leadership O the Polish General Zeligowlsi the territory was recaptured and it was during the occupation the stamps of Central Lithuania came into being. Subsequently the territory became a part of Poland."
So these are Central Lithuania, and the Polish occupation explains way the name Poczta is on them.
There. Learned something.
