|This box is marked "Spaulding Ware."|
Spaulding Ware made lots of melmac and plastic ware, and here on my Spaulding Ware history page I did find a set of spice shakers which I thought was odd. I heard rumors they made kitchen ware, but this doesn't explain a sewing style box.
As with most plastic companies it is not uncommon they did contract jobs for others, aside from melmac dinnerware. However, what was this contract for? A sewing company? A craft box? A novelty box? A canning jar box?
You never know, do you? It never ceases to amaze me that out of the blue or woodwork something will come up that you just don't see everyday, even after all these years of collecting. For now PaperFranks is enjoying the box but sooner or later it may end up in their PickOhio Etsy shop so keep looking.
