Background - is a really clean store display easel card offering Scripto erasers for sale. I'm guessing pre-1950.
Top - is an American Pencil Company #48 Success model. It's a combination device with reversible eraser/dip pen on one end and mechanical pencil on the other. Cool piece!
Right - is a gold fill Eversharp repeater, made in USA. Call it 1940'ish.
Bottom - is a first generation Sheaffer's Sharp Point in sterling, c.1920.
