Advice of Receipt from Armenia

Sent from Yerevan, Armenia.  



It's an AR (Advice of Receipt) originally from Singapore.
When my friend received the registered mail, he signed the AR and sent it back via their postal system.


I sent it at Mar.11 and he got it at Mar.24.
Looks like the postal system between Armenia and Singapore is reliable.

One more thing, the postmark from Armenia is special.
Use an arrow indicates the time.
