Jared Farmer has made available, for free download, two self-published digital collections of Mormon-related images. This is not really a review—it’s an endorsement.
Mormons in the Media, 1830-2012 has 500+ illustrations with some explanatory text. JJohnson reviewed it for JI last August. The edition available for download now is not marked as a “2nd edition” (as of June, when I last checked) but it has some minor, silent corrections.
The Image of Mormons: A Sourcebook for Teachers and Students has 700+ illustrations but almost no explanatory text.
Hie thee to a web server and download, forthwith.
