Group of 5 Animal Woodcut Prints by Naomi Stoney - 1920's/30's British / Australian Artist

I have a superb group of original woodcut prints , dating from the late 1920's to early 1930's . $ are by Naomi Stoney and are signed and dated apart from the Swan print. Another kangaroo print is signed " T.Stoney" although it is the exact same print as the Naomi Stoney one. I have no idea why ? All framed and ready to hang , the largest measures 31 x 38cm to give and idea of scale. The Britihs Museum and Victoria and Albert Museum hold examples of her prints , which 2 of mine I'm listing are the same ones as in the museums.
