Nell Walker Warner Original Watercolor "Still Life Daises and Mums" Signed "Nell Walker Warner" Lower Left

I have a Nell Walker Warner, that appears to be a original watercolor. i don't believe it to be a print. I am not able to find anything about it via my search (also done with a photo) I did find an Oil on Canvas "Still Life Daises and Mums" Signed "Nell Walker Warner" Lower Left that it is close to identical to it. You have to look close to distinguish differences - but not too hard to see shading and shape differences. I don't believe it to be a print because it short and wide as oppose to the oil which is tall and narrow; nor can you see any canvas in it as you can in the oil painting, Also the signature is different. I am curious if it is known to be an original watercolor of hers (vs. a print) and what the value might be

Good
