Three Waterman's Ink Bottles.

Three Waterman's 2 Oz. Ink Bottles 

of the Same Type Shown From Different Angles.

Waterman's Pen Company was founded by Lewis Edson Waterman in New York City in 1884.  

Bottoms of Same Three Bottles.

Of course the bottles changed over the years, but bottles of basically the same shape as those shown are still sold today.

An old barrel shaped Waterman's ink bottle is shown in another post on this site.
