I don't know, sometimes a rusty old can just strikes me, as did this one, with its red, yellow and blue graphics that look very carnivalesque. The reverse side reveals that this Ruby Rub Oil Metal Polish was manufactured by Hinds and Coon of Boston, MA--a business which seems to still exist, though no longer on Pearl Street. I found out there one image of a receipt from the company dated 1910, featuring a Ruby Rub can looking very much like this one as part of its logo, so would guess it dates to around then. It still has some polish inside of it I believe, but the cap is rusted on so there it will remain! 

5 1/8" t x 3" in diameter. Aged and rusty as evident but I think it's still pretty great looking.
