There remains a popular myth that Lincoln wrote the
address on the train en route to Gettysburg, Pennsylvania. Train
travel did not lend itself to writing, since the train cars were
unsteady in their movements making it impossible to write with clarity.
The Lincoln National Life Insurance Company in Fort Wayne, Indiana,
as an insider joke, reproduced a Lincoln-era envelope and then printed
a facsimile of the Gettysburg Address on the envelope.
