Now on to the star overprints with cancellations.
A)
Starting with “A” On the left fragment is “LIS” – perhaps Elisavetpol Gubernia or Tiflis? Long tailed serial “a” – I’d say.
B)
“AG?” “ELISAV.” Some town in the Elisavetpol gubernia. And long tailed serial “a” here too.
C)
Again starting with an “A” and ending with “BUL”
D)
Beats me…
A.= AGDASH ELISAV , AGDAM ELIS or AKSTAFA ELIS
B = AGDASH ELISAV
C = ADZIKABUL BAK ( not common)
D = Should be possible 🙂
