Esterbrook - Est. 1858 Reborn 2018 (The revived old American brand) Esterbrook was founded in New Jersey in 1858 by Richard Esterbrook, an inventor and businessman from the UK. Used by US presidents and writers, it is also known that J.F. Kennedy used it to sign the budget for the Apollo program, which sent humans to the moon, in the 1960s. As a writing instrument representing the good old days of America from the 1930s to the 60s, the so-called modern times, it produced over 20 million fountain pens annually in the US and the UK. About 50 years after closing its history, in 2018, its name can be heard again in New York. This item was purchased overseas, so there may be damage to the box. Please understand this beforehand.
