The American Naturalist was first published in March 1867. Over the last 150 years, AmNat has had 16 different covers. Below is a gallery of those covers, with the dates they were used. Click on any image to bring up the full-sized gallery.
One of the fascinating features to trace through the covers is how the motto of the journal changed through the years.
