The difficulty I have is in interpreting what is meant by "no-panes". The artwork could be just simulating many windows on the left side and the low resolution of the reproduction on the inlay just showing a mass of lines. If the "with panes" note is intended to designate the art where a few panes are shown in detail while representing the hundreds of windows that are actually in the building, I can understand. I have heard several collectors say that the difference in the building pictures are that they represent "before and after the bomb blew out all the windows", which I don't think is correct. I doubt the artist intended the mass of lines in one view to represent a lot of broken windows.

I'm suggesting that some of the other differences in the two kinds of artwork be used to distinguish them (like size of some of the type and dollar sign placement) or that a picture be referenced in a note at the back of TCR.

Now that we have the pictures in TheChipGuide to look at, it may be sufficient to have TCR authors simply confirm that the Harvey's chip pictures and TCR catalog numbers are properly matched up on the web site. These building pictures appear on several different denominations of the series. The $2 chips have recently been re-numbered in TheChipGuide to match the interpretation you stated.
