Maximilian recorded in his journal that on August 7, during an outing along the Lehigh River, several bullfrogs were captured and that "Mr. Bodmer made a sketch of two of them." He explained that such lively specimens were tied down with strings to hold them in position while Bodmer executed his careful studies.

Returning home on December 31, 1832, from a visit with Say, Maximilian found that "a fine and large otter" had been delivered to his door by one of the local hunters. He subsequently bought it to add to his North American collection. He does not mention Bodmer's sketching this particular specimen, but an inscription identifying the subject of this drawing as indigenous to the Wabash suggests that it was made during the artist's stay at New Harmony.
