Hi Gary,

Thank you for contacting Mearto with your appraisal inquiry.
Not much is known about the artist, though she may have been living in Florida.
The only recorded previous auction sale by the artist was this work, which sold in 2018 for just $25 though it had been estimated at $200-400 (https://www.liveauctioneers.com/item/60132133_susan-parker-rachanski-acrylic-on-canvas)
Your painting is considerably more detailed that that work, and is much larger. I think the work previously offered was overvalued but a similar estimate - $200/300 is appropriate for your work.
