I am sorry but I DO NOT KNOW IF IS ANTIQUE AND IF IS AUTHENTIC, this is why the price is very low. I bought in EBay many years ago.

Gentleman wearing what looks like a white cap with blue jacket and rather extravagant waist coat, resting beside a tree with a Cocker Spaniel dog. Dimensions: 25cm X 16cm - Some painting missing, minimal cracks by age. 

Please see my other beautiful items!Thank you!
