The Crest for the PIEs

I was thinking ... what would the "perfect" heraldry symbol for the
PIE community, or a possible pan-symbol used by the PIEs.
Well, ..ofcourse we may not know for sure, but it won't hurt to have
an idea of what "ethnic symbol" they had to identify themselves.
Much like my post on Indo-European for Indo-European.

Or, if we have really no "exact" idea, we, modern Euros, can give
our own proposals for an IE heritage symbol on the Pan-European
crest. Nothing "Nazisistic" here!!! Just give your proposals (based
on whatever evidence we have!).

I suggest:
1. an eagle
2. a horse
3. a cow -- a IE sacred beast
4. a cross -- which has been an ancient sun-symbol
5. a lion?????

What do you think?

Peace out,
