A couple of issues before the Relativity, the Romulan Bird of Prey will be only the second TV-era TOS ship in the series so far. When Ben tweeted these images he noted some of the work done to make the big bird motif look just right: "A LOT of effort went into adding grain to the bird pattern."
Ben also posted the first ever images of the ISS Enterprise, a variant of the recently released USS Enterprise model, which will be released separately from the regular series as an extra issue. This variant features different print details appropriate to the mirror universe ship, plus new nacelles, complete with spire-tipped caps. Ben noted that if this first mirror variant does well, a mirror-NX-01 is also possible.
Ben regularly posts previews from The Collection on Twitter, definitely worth a follow. For a listing of all the ships in the Starships Collection, including links to all my previous previews and reviews, see my index page.
