Finland or Lithuania

FI-2196425 (?)

Vilnius

This card is a bit of a mystery to me.  It was mailed to me by someone in Postcrossing and I suspect it may have been one of 3 cards mailed in the above official postcrossing card in an envelope.  I can recall what the other two cards were fairly easily, but the third one escapes me.  Due to circumstances and the process of elimination, I'm pretty sure that the third one was this one.

This would be odd since the card is of Vilnius, Lithuania..which isn't Finland.  The card is blank, but lists the image as "The office building".  The card itself seems to have a date of 1990 on it, so it may predate the fall of the Soviet Union by about a year or so.

It is clearly a card of some mystery.
