This L5 imprint is the only use of a Carpenter design from Minnesota that I am aware of.

L5 imprints are most commonly found on checks from Pennsylvania. The imprint on this one is superimposed upon an all-over vignette, which is rather unusual.

L5 on a used draft from Kirksville, Missouri calling on a New York financial institution for payment. The vignette does not look like it is a scene from anywhere near Kirksville.
