Veil of Veronica Linen Relic

Picked this up today. It was in a old plain looking frame. I've seen a variety of these when researching, with different text styles and sizes. This one is hand colored which seems a bit uncommon. It measures 14 3/4 x 11 inches. Pricing is all over the place also. Is there a way to determine timeframe and maker on these? Does it matter?
