The Argo is very, very infrequently depicted in ancient art. I can only think of two definite examples, both from the Classical period (5th and 4th centuries BCE), when virtually all ships would be shown as triremes. They are: a copper jewelry box (cista) called the "Ficoroni cista," discovered in Italy in 1798 and now in the Villa Giulia collection in Rome. It shows a trireme: link

The other is a bit of the art on the Sikyonian treasury at Delphi, which is extremely fragmentary, and I can't find a picture of it on google at the moment. It also shows a typical trireme for the Argo.
