Pencil Box by Amber MFG.

Another great pick....a wooden pencil box that slides open and has a 9 inch ruler on the side. On the lid it reads EAT MOTHERS IDEAL BREAD PIES CAKES COOKIES QUALITY SERVICE SATISFACTION....and in very small letters above the word EAT it reads Amber MFG Concern Falconer NY. Anyone with any info on this box...year that that were handed out as promaotional advertising?? Is it a rare find....collectable??? Thank You
