Tretchikoff's Weeping Rose

Is this an original or a copy?  If it is a copy, how many copies exist?  I used to own one identical to this and would like to know if this is the same one. 
I would also like to know the value if good or excellent condition as the one above. The age of my copy was approximately 35-38 years old. Frame is same as the one in picture above.

Thank you!

Vladimir Grigoryevich Tretchikoff  26 December 1913—Old Style 13 December—in Petropavlovsk, Russian Empire, now Petropavl in Kazakhstan[1] – 26 August 2006 in Cape Town, South Africa) was one of the most commercially successful artists of all time - his painting Chinese Girl (popularly known as "The Green Lady") is one of the best selling art prints of the twentieth century.[1]

Tretchikoff was a self-taught artist who painted realistic figures, portraits, still life and animals, with subjects often inspired by his early life in China, Singapore and Indonesia, and later life in South Africa. His work was immensely popular with the general public, but is often seen by art critics as the epitome of kitsch (indeed, he was nicknamed the "King of Kitsch"). He worked in oil, watercolour, ink, charcoal and pencil but is best known for his reproduction prints which sold worldwide in huge numbers. The reproductions were so popular that it was rumoured that Tretchikoff was the world's richest artist after Picasso

There is more prints and copys of this picture, its mind boggling that it is still worth something..condition and the way its framed.. "NOTE" when taking photos of something please take as many photos as you can post. it helps.. 

most sell for less then $50.00.. but I think I would put a higher price and see what offers you get. again Condition is EVERYTHING! IF THIS IS A PRINT..you said it was canvas? CLOSE UP OF PICTURE a must see.. Question? do you know the diff. between a print and a real painting? look very close for printing DOTS
