If it can be blazoned-- it's heraldry:

azure, issuing from the sinister side of the shield a zebra's head couped at the shoulder, proper.

So there. Advance it on shield and banner without the let or hindrance of any manner of man or men, whatsoever.

If you are thinking of adding a mound to the base of the shield, I'd suggest that you have the zebra forcene (that is rearing up on it's hind legs) on it, as this will add better balance to the over-all design.
