First: If u look to this pic you'll see:
" All Done With A Single Stroke of The Pen "
" copyrighted 1884 , by the publishers, Knowles and Maxim "
I believe the single line, but I have my doubts as to the claims of “a single stroke”. The
ball point wasn’t patented until 1889 and this has an 1884 copyright. I believe barrel-fed nibs came alone even later. This means the nib would need to be continually re-dipped.
