Happy Friday, history lovers! Doing anything creative this weekend? This Musicwriter "typewriter" was manufactured by R.C. Allen of Grand Rapids, Michigan, during the mid 20th century. It was used to compose sheet music. Instead of a letter-writing typewriter, each key could print a different type of note, which could be raised or lowered on the musical staff. ? #music #creativity #innovation #technology #TGIF
