These are photographs taken by Harris and Ewing, Inc. They are in the "Harris and Ewing: collection of the Library of Congress, Prints and Photographs Division . They are all in the public domain (as are the versions of them here).
The digital versions here take several forms, as explained for each. Since the Library of Congress URLs have changed at least once, instead of citing the URL of the original image, I'll cite the call number.
Archie Lockhead reported directly to Henry Morgenthau, Jr., the Secretary of the Treasury. At least one contemporary report indicates that he kept track of the markets and currencies for Morgenthau (Lewiston Evening Journal, 1935-02-15). As other photographs in the Harris and Ewing Collection show, his office was across the hall from Morgenthau's. Given his position, this was perhaps one of the most important Teletypes in the world at the time.
Lockhead's Office, Teletype and Tickers
"Archie Lockhead's office force with stock & bond tickers, 2-23-39." Call Number: LC-H22-D- 5906[P&P] February 23, 1939.
The Harris and Ewing photographs have been scanned at quite high resolution. This gives several options for re-presenting them here. If you click on the icon/thumbnail at left, it will open a reduced size (but still a large, 2048x1640 pixel) version of the complete image. This is a good general view. Below, I've included one other views and two full-resolution versions.
This is a close-up of just the Teletype. I find it interesting both because it shows the Rectifier unit below the Teletype itself and because it shows a fan (clearly running) directed at the ventilation openings on the Teletype. The PNG linked from this thumbnail is full-resolution (but see the notes below on the processing of the TIFF originals).
The Library of Congress originals are supplied in TIFF format. However, TIFF is not in fact an image format at all, but rather is a container format. In the case of the Harris and Ewing images, it turns out to be a container for raw digital photographic data. Before the image can be viewed, it must first be rendered by an appropriate raw photographic filtering program. In the versions here, I've simplified this process and just rendered it using ImageMagick's "convert" at the default settings. Here is that conversion, full-resolution, together with the actual original from the Library of Congress. Should you wish to work with the TIFF version, it would be best to download it and process it with, for example, The GIMP (as if it does render in your browser, your browser will be making conversion assumptions about it). Both files are very large. Isn't digital imaging fun?
The Harris and Ewing Collection images here are in the public domain. The digitized versions of them at the Library of Congress and the re-presentation of these here remain in the public domain.
