Mid century modern water color PAINTING style of John Lennon 1960’s 1970’s MCM Paintings

Mid century modern drawing water color John Lennon style era 1970s 1960s MCM painting. Total dimension w frame 22.5″ x 19.75″ …. I think that is the signature just to the right of the hips ?? It is a real work of art and not a print… in gorgeous double blue matting with thick rounded edged chrome frame. No damage to art …. small scratches near bottom left corner on top of frame surface. Purchased it from an estate sale …….. fell in love with it instantly. Looks like the style of John Lennon. …???? On the back someone scratched out the two names of the people who framed it. 27 years experience ……. super safe shipper. $500 or best.
