You can't really say that about this year's stamp, as a rooster on a red hongbao is the main focus. There's also a gold rooster top right.
Here's one on an envelope from Mary.
And a printed one on a KFC bag from Jean that was inside another envelope.
And finally, a beautiful rooster stamp on this postcard from Eric.
Update: the French stamp is issued as a 'Monde' or overseas stamp, as well as part of a 12 stamp domestic set, one for each Lunar Zodiac Animal - the set is beautiful.
Bonus rooster from MailArtMartha, that spent a long time in transit, was delivered back to her, and finally made it.
