Going through the movie looking for all the shots of this sign. Let me know if I missed any other angles.
I never noticed that the only time we see this particular side of the sign is in the first shot of it, when Winston is applying for his job. I will refer to it as side A in the collage below.
All the other shots I found show the B side. Such as in this shot that comes in between Venkman at the fountain at Lincoln Center and Ray explaining how the containment unit works to Winston.
There's a great closeup of the B side just before Peck shows up to shut off the ECU. I think this one really shows just how close to the 'flat logo' they actually got the dimensional sign.
Comparison of A and B sides:
Back to the movie. The action then cuts directly to a wider shot of the all the vehicles screeching up outside the firehall.
[I noticed this shot was VERY similar to the earlier shot just before Ray explains the ECU. Sure enough, when you compare them one atop the other, they're framed almost identically.
The guy in the trenchcoat can be seen in both shots, and the shadows on the side of the building don't appear to have moved, so apparently they trimmed the very beginning of this take off and used it for the earlier establishing shot.]
Perhaps the only 'straight on' angles of the sign occur when everyone is running out to escape the ECU explosion. Too bad they're not closer in.
And unless I'm overlooking something, the last time we see the sign is in this shot. I don't think the audience is shown the firehall again in GB1 after this moment.
It's the only shot of the sign from above, but is even farther from camera than ever.
So here's the collage that I made, just to see all the angles at a glance.
