This sheet contains a complete set of keys from a vintage Royal Standard typewriter. The diameter of a letter key is about 1/2". I have also included some images of typewriter-related stuff as well as some text in old-fashioned typewriter fonts. You can also purchase this alphabet together with a Remington typewriter alphabet in a full sized sheet. Click here to find out how to order either full or half-sheets. (Also, if you have an interest in old typewriters, I recommend you check out this site on Antique Typewriter Collecting. It has pictures, historical information, classifieds, and other cool stuff)
