Here is this week's release, we hope you enjoy it!
On the left, we have a publicity photo taken in the late 70s, most likely for Star Trek: The Motion Picture. Note the Enterprise shadow on the wall behind Gene - made by a strategically placed model (that it almost appears Gene is looking at). The shadow is very indistinct, but the rounded nacelles appear to suggest the model is of the original series Enterprise.
On the right, is another photo from around 10 years later, which looks to have been taken at the Roddenberry home - probably an early publicity shot for the (then) upcoming Star Trek: The Next Generation. In this case, an image of the Enterprise-A is seen on the wall behind Gene, a nod to the previous ship in both cases.
