I have a painting that my grandfather gave me and I'd like to find out
who painted it.  I can't make out the signature -- it looks to be in
either Greek or Cyrillic letters -- so I can't Google the artist or
try to find him/her on eBay.

The painting is a modern oil of a wharf or a pier and a cityscape. 
You can see a picture of it here:

I have taken a close-up picture of the signature, which I have
enhanced; that is viewable here:

Any and all help would be appreciated!  I'd like to get this mystery solved!

I don't know, but I sure do like it!  :)

I think it's very cool, too, which is why I want to find out who
painted it!  It's a definite mystery -- although I hope that someone
will be able to help me and figure it out!

Hi!The name is Greek and its P. Zografos. Zografos in Greek means
painter so I guess it was his artistic name.I m taking a wild guess
that P stands for Panos or Panagiotis.
I did a bit of a research on the name Panagiwths Zografos and
eventually was one with that name. You?ll find some infos about him in
here http://www.mlahanas.de/Greeks/Arts/Arts.htm and you can see his
artistic style here
http://grecja.home.pl/malarstwo/mal_zografos.htm .Though I m not sure
at all if that?s him because the painting seems contemporary and he
lived in the 19th century..But the name is for sure Zografos
(????????).If you can give me more details about the era the painting
was created i might be able to help you a bit more.

Danae, Thank you so much for your comment!  I really appreciate your
translation of the Greek...

I'm not sure of the era of the painting, but I agree with you that the
style of the painter you mentioned didn't really match.  This is,
however, a starting point...

I'm going to call my father tonight to see if he remembers anything
about the painting.  My grandfather was the C.E.O. the American
Manufacturing Corporation (AMF) in the 1960's and 1970's, and he
travelled frequently.  Perhaps this painting came from one of those
visits?

I'll post more later...

Style influenced by cubism?

Here is a paper about Greek art that covers the period.  Panos
Zografos's style is quite different.  Could the artist have just used
his initial "P" with the word for artist - or been so devious as to
ride on PZ's coattails?

At the end of this site, there is a list of galleries that might be
able to add some insight:

i have to say one more thing.I m not 100% sure that the name starts
with P i m just guessing because it hes been paint very artisticlly
and maybe i m wrong.For sure the surname is Zografos.I haven't found
something more..

Actually, I don't think the initial is a P at all. It looks like an O,
which would be unlikely, as very few Greek baptismal names begin with
O; possibly a theta without the central bar, which is also unlikely;
or, which is my guess, just an ornamental flourish on the initial Z of
Zografos - which doesn't, unfortunately, help very much...
