Pretty much.

And where did it come from?

I know a little while ago, someone started tracking the X-wing alternate art cards which was neat to see. But the early stuff was a bit fuzzy.

So starting now to avoid that.

Lets group think this list together.

For the June League kits there is the "Movie shot" Nebulon-B escort frigate as a participation prize, and a few VSDI "Art" shots

I got like 6 Neb-Bs and only one VSDI, plus a forlorn concentrate fire acrylic token

I don't have a VSD2 alternate art card. . . Summer kit has a Tie Fighter and Assault Frigate Mark IIA

You can get these on ebay. I personally can't justify spending money on such a thing, but the option is there if you're interested. Nebulon card goes for $3 a pop, VSD is usually around $20. I Imagine the TIE and AF are respectively the same.

Couldn't find the TIE fighter. I know I saw it at some point.

The Nebulon and VSDII cards came in the spring game night kits.

The Assault Frigate MkII A is in the summer game night kit, along with an alternate artwork TIE Fighter card. My store put the order for the summer kit in as soon as it was announced and they have yet to receive it.

As you can see, there are 2 Assault Frigate cards for every 17 TIE Fighter cards. The same is true for the ratio of Nebulon B cards and VSDII cards.

My local store runs an Armada league where the Nebulon B card is a participation prize for everyone, and it started the week the core set came out. I probably have 10 copies of the card by now, and that is after giving away some of them to friends.
