Vary large painting 62 " wide 32 " tall. Ink wash on rice paper, the Chinese litters say its called 8 horses, on a summer day, date of painting not sure but any where between 1926 and 1987, I am not sure who the artist is, if its in the Chinese litters or the chop marks. It looks like art work that Xu Beihong has done of horses.
Unknown, i bought it from an estate.
I haven't been able to identify the seals on your piece. Yes, if it were an authentic Xu Beihong, it would be extremely valuable.
The likelihood is that this is a copy of Xu Beihong’s work by a different artist. I am basing this on the fact that the horse’s poses in the work are copied from two different Xu pieces. The calligraphy style looks slightly different to me as well.
My advice is to send a picture to Christie’s since they have handled authentic Xu works, I think they can give you a definitive answer.
As for valuation, if it not by Xu Beihong, it is still a fine painting and would be worth between $600 and $1000 based on paintings of similar size and quality.
A real Xu painting would be in the millions.
Please let me know if I can be of further assistance.
Here are some of Xu’s seals:
