Thank you for submitting your item for appraisal. This appears to be a painting by the former irish dance star Michael Flatley (* 1958 ).
There is no way to authenticate such a painting due to the coincidental painting technique. Assuming you have a receipt from the artist, the estimate is as listed.
There are very few auction results of sold paintngs currently, a solid market value is not yet established. "Asking prices" can be much higher and vary.
