If you're a Rom, Spaceknight fan, you've no doubt seen this piece of art before, but probably not in its complete, original form. For example, a cropped version currently Rom's avatar over on Twitter. So what is it, you ask? It's shelf art! Parker Brothers sent them stores for their Rom displays. As it says, the yellow "T" was T-tacked, taped, or otherwise attached to the shelf and perhaps folded so that the "ROM is here!" sign was prominently displayed below and/or above the boxed action figures.
I have no idea who the artist for the shelf art is; likely a staff artist at Parker Brothers. However, it was obviously redrawn for the small house ads that Marvel ran as they were launching the Rom comic book. Honestly, I don't know who is behind the house ad art, either, but likely suspects are John Romita, Jr. (who drew the presentation page for Marvel's proposal to Parker Brothers) and Sal Buscema (I don't have to tell you who he is, do I?). Or possibly it's the other way around, as Rom's head in both is how he appeared in the comics, which is slightly different from the action figure's.
The shelf display above and 180-day limited warranty below were sent to me by Max Thorne. Both pieces of paperwork came from unopened boxes of action figures. The wording of the warranty is identical to what appears on the last page of the action figure's instructions, just formatted to a wider width.
And for reference, here's how Rom was shipped to toy stores back in the day when it was new: six action figures to a shipping box. Sadly, I've lost the information on where I obtained this photo. Possibly it came from eBay.
