It is optional.  PGP >= 5 emits it as first packet so that pgp2 bails
out on such a message.  GnuPG does not care or emit this packet.  I
have suggestet to enhance this packet to reflect the version number of
OpenPGP so that a software knows why the message fails.  We will see
whether we can put it into the next OpenPGP release.

It has just the contents "PGP" in ASCII and a length header saying it
is 3 bytes long.
