Here's a pic of what I found. I was north east of Acroplolis, just walking down the street and noticed this on the ground. Probably not historically significant but you never know. Appreciate any insight people are willing to share.
Without knowing if this is a replica or not it is a bill of exchange for 1000 drachma (the old currency of Greece) to Spurion Ilios (maybe, the surname is very difficult) who lives on Phokai 10 in Athens.
Dated 15th September 1973.
I think. Greek banking is not my speciality.
It seems to be a check to be paid up until 1 year after its emission. The check was emitted on september 15th 1972 and can be cashed until 15th september 1973.
It is to be paid to Spiridon N [I cannot quite read the other part], in Athens.
There are five 1 drachma stamps on the left side, and the amount to be paid is 1,007 drachmas. The payer seems to be a certain Vasilios Kontobrios.
