Larry,
Glad you like the blog! The photo of our original building does make the building look narrower than the illustration does. We don't have any records of how the building was modified during out tenure there, but clearly the artist made a few aesthetic enhancements in the depiction of the building and the setting. The footprint of the building is drawn as being narrow on the Sanborn map that's shown in the post. Also, the angle of the photograph probably makes the building look narrower than it actually was. Regarding the museum, please send me an email.
