Shipboard Radio Room, 1913
It's an ad for Fatima Cigarettes, and it appeared in the January 25, 1913 issue of SCIENTIFIC AMERICAN.
I'm not going to make any assumptions about the accuracy of the equipment shown here, though it was undoubtedly drawn by an artist working from a photograph of an actual installation. The two-color printing works pretty well here, in contrast to some of the other ads from this series (click here and then choose "next" to see some more). As always, click the image for a larger version.

Sears, Roebuck's 1922 Catalog of Electrical Goods and Radio Apparatus
As some of you know, I run a small e-publishing company (first book, 1999, so we were pioneers). Steve Davis sent me some scans from his copy of this 64-page catalog from Sears, published just at the moment radio was changing from a hobby for experimenters to a mass medium of entertainment for the entire culture. Here's the cover (click for full-size version):
The first sixteen pages of the catalog are devoted to electrical appliances, and are lots of fun to look at. It's surprising how many home housekeeping functions were covered by things you could buy in 1922; and some of them had been available in one form or another for two or three decades by then. The radio interest begins on page seventeen, and continues until the end. Most of the entries are components, but there are modular chunks for assembling a complete receiving set, and even a couple of fully assembled modular packages. Here's a typical page (click for full-size version):
This was so cool that I talked Steve into scanning the entire thing, so that I could publish it as an e-book. It took me two months to clean up all the background trash on the pages (they're printed on cheap paper and the catalog is ninety years old), figure out how to format it so that it would fit in an e-book package, and get it uploaded.
It's now on sale in ePub format (for any ebook reading device) and in Kindle format (for Amazon's hardware). You can buy it on Amazon, Barnes and Noble, Google Play, and at the Apple iBooks store (search terms: Sears 1922 radio catalog). It's beautiful, if I say so myself, and it's $2.99.
Yes, it's cheaper than a latte.
There is no DRM (!). You can print pages out. You can lend it. You can even sell it, if you should be so internally damaged as to want to.
Obviously, we're not doing this to get rich. It just looked like something I wanted to own a copy of, and this was my rather involved of doing so ... with the result that you can own a copy, too.
One extra neat thing: if you are reading the book on an iPad, or on a software reading app on your computer, and even on certain hardware devices, you can double-tap the page or stretch the window to make the image very, very large. You can make it large enough that you can read all the little tiny type on all of the pages.
Getting this feature to work was one of the things that made formatting it a challenge. Although ebook reading devices nominally have small page sizes, the underlying image can be larger in number of pixels, as long as you don't go over a file-size limit. This book pushes all those boundaries. All the work I did in Photoshop to clean up the pages, to make the edges clear, and to minimize graphic artifacts collided with the file-size limits, and by sneaking around these limits we've made every page readable in complete detail. (Though you do have to read it on the right kind of device; on your iPhone it may be just a little bit too small no matter what.)
Buy a copy. Tell your friends. Did I mention that the two images in this blog post (large versions) are the images we used for those pages in the book? Click to make them big (limited by the size of your display, of course), and see what you think.
