This is a lovely mid-century never used vintage linen tablecloth with the Belgium label still attached.  It was stored with other linens for many years.  It is a beautiful candlelight type color but there are some light age darkened areas.  They are light and I would use it just as it is, because the color and room lighting would work to make it look fine to me.  I took it outside to the sunlight and made photos so you can see the slight shading differences in spots.
