Hellenistic Banners & Standards

I guess a lot of people know the Roman eagles or the "boar standards" ;)

I'm wondering about the Seleucid, Ptolemaic and all the other "hellenistic" states. What type of standards/ Banners did they use?? Are there any reliable sources that deal with this subject? If so, I'd be interested to hear about them.

I know this isn't directly related to EB but i was wondering and i thought it could be interesting ;)
