One “curiosity” though, is that the very last image showing C.G. Conn’s private office has what appears to be a March calendar on the wall. Perhaps the photo was made in 1910, in which March 30 would have been a Wednesday (March 30, 1911 was a Thursday).
However......March always has 31 days, not 30 as shown on the calendar. It doesn’t appear from the website image that anything is covering a 31 date. Anybody have one of those original cards, and able to make out a different month....or perhaps something is shown covering the 31 date on a higher-resolution image
Cropped portion of that image is shown below:
