Little d knows my fondness for old typewriters and she picked up a gem from a co-worker. I'm now the proud owner of an army green, heavy-duty Oliver typewriter that sports showy batwings. I had never heard of this particular brand and naturally I did a quick search on Wikipedia:The Oliver Typewriter Company was an American typewriter manufacturer headquartered in Chicago, Illinois. The Oliver Typewriter was the first effective "visible print" typewriter, meaning text was visible to the typist as it was entered. Oliver typewriters were marketed heavily for home use, utilizing local distributors and sales on credit. Oliver produced more than one million machines between 1895 and 1928 and licensed its designs to several international firms.
