Norah McGuinness – the real thing?

This interesting untitled work attributed to Norah McGuinness sold for just £134.00 on eBay on the 5/9/2020. Despite being signed it was sold as attributed to the artist which always rings alarm bells but, that said, it looks like the real deal to me when compared with similar works by the artist. If it is genuine,  I suspect that it will soon turn up in an Irish saleroom with a very different price tag.
