Technically this is actually a coat of arms. I myself am not familiar with this one. Where did you get this image?

Not exactly a logo, it's a seal/coat of arms. It seems to consist of at least four themes, which could represent families or cities.
I'm no expert on heraldry, so can't really help you there.
Where is it from? Country of origin might help those who know more.

[edit] Ah, Miss T. got there before me!

Well i got this to make vector art from my customer...........and bad news is that nothing else information or image i m getting from him or else. so looking for help from u guys.....

This is probably a specific families coat of arms. If you knew where the photo was taken that would be a good clue. It might also be good to know if it is your client's family's coat of arms. If it is a families coat of arms chances are that you are going to have to draw it. You'd save time by just re-drawing it yourself.

It's cheap. Buy it.

Probably an ornamental fence, gate and alike. See, for example, the brown paint/spray.

The picture is an ornamental keystone. It marks the apax at the crown of a vault or arch (I don't dare to say which). A keystone locks the other pieces of a vault or arch into position.

This is one coat of arms (one family). The shield is made out of two 'important' families (the red and white) because of a marriage between the two (red and white) creating one family thus one shield (one coat of arms).

If the vector art is going to be in black and white there are rules how to represent the colors (the color silver is a doted pattern etc.). You can look it up in a book or ask your local genealogy society (you can ask your local city/village museum if there are any or at city hall).

The helm and mantling are also significant, but I can't recall why.

Best of luck.

There is a great Wikipedia article on ways of identifying and representing tinctures (heraldry colors).

We might be of a bit more help if you mentioned the country of origin.

Hi friends
i have made this logo vectorised. I want to know your comments on this. Attached image of the vextorised file...... If you thimk is there any suggestion pls let me know..........

I think It's an italian coat of arms. It's also related to Venice. That lion at the bottom is the protector of the city.

Lion is associated with Saint Mark, that's the Venice connection. But something tells me that's not the only association.

That lion needs some work. I just watched the South Park episode with Mr. Garrison and the mouse and the genetic experiment escape. I'm having flashbacks.

The helm needs more detail, it's getting lost in the mantling.
