Thank you for submitting your item for appraisal. This appears to be a Venetian Jerusum hand embroidered tablecloth with bobbin-lace measuring approximately 100 " by 63". Lace-making has a long tradition in the Venice region and came into vogue again after the unification of Italy was completed in 1871. Micheangelo Jerusum employed skilled women in the Venice region to create highly acclaimed Venetian linen since 1870. The beautiful tablecloth in your possession has a brass medallion proclaiming its creation by Jerusum. The estimate is based on similar items offered or sold at auction. There is no measurement for the sentimental value you might attach to it.
