Knowing that helps greatly !! I would go for Mission Bell and probably made in Mexico !! For that price on the inside,, try a standard pencil eraser and see if it was done with a chalk pencil,, unless its a paint and if it seems like a paint (hope its water based) lay it on its side and put a soaking wet cloth (warm water touch of dish soap) on top and let it sit for at least 30 min !! Keep the cloth very wet during this time. Then see if the paint is lifting,, you should be able to rub it off or use a soft toothbrush to lightly scrub !! If that doesn`t remove it you may have to use lighter fluid and Q-Tips to get it off !!
