From today’s Patch 2.9A notes:

The “Republic Voss Embassy Sign” item from the Gatekeeper’s Pack now grants the correct Decoration. The item is also available from the Binary Star Reputation Vendor for 1 Credit for a limited time.

Go. Go and buy them.  Now. Do it.  Buy 50 of them. GO!

EDIT: They’re gone now folks. Grats to those who got em while they could.  If you want them now, they’re back in the packs.
