It may well be - however, be warned that this is a hard time to be trying to get good value if you're a private person looking to sell. it's damned fine work (the layers on the flower petals boggle me) and slightly yellowing is acceptable in older pieces. you can wash it, gently, by laying it in the tub with warm water and a tiny bit of shampoo or detergent for delicate fabrics, and letting it soak for about 10 minutes. oddly enough, the best whitener? is sunlight an chlorophyll, so if you have a CLEAN lawn, or a nice soft bush to drape it over, that's not a bad way to dry it. this one, by the way, looks as if it's been very lightly used - the thread has not 'fuzzed' at all from being washed, and it looks like it still may have sizing in it (they were often starched after drying)

the only thing i know for sure is my dh's grandparents bought it new in 1948 according to the mfg's tags

I do believe I have the pattern you are looking for. I made it for my mother-in-law. I will be more than glad to send you a copy.

You need a 70 inch round cloth....or a little smaller....but 70 inches is a standard size. Amazon for one place will have lots! Linda C
