These are certainly a fine 1971 rendition of the Albrechet Durer Adam and Eve paintings that were originally completed in 1507. There is little transparent information on the artist Rosario Dawson available other than she is from Spain, born in 1940, and likely still alive. Here is a link for you to a self-portrait of the woman who painted your Adam and Eve panels.
There is also not a transparent past auction history of her works being sold to public. Conservatively, and based on comparables, a fair price is $2000 - $4000 for the pair with a suggested insurance or replacement value of $6000.

Copyist paintings based on famous works have been used in Academic Art settings for several centuries. A classical representation and realist figurative artist who wants to perfect their ability will sit in a museum and try to paint as close as possible to a famous work by a Master artist. It is not uncommon when visiting top National Museums throughout the world to see artists seated in front of works trying to paint their own best rendition.
