I have spent some time looking at the internet to see if I can find any information, but without success. I suspect that your item may either be a good quality oil print or possibly an oil painting from one of the Chinese painting factories Search on Dafen painting factories to learn more about these. The reason I suspect this is because your label sounds as though it might be showing a serial number or a stock number, and this is common on the items I have just mentioned. However it could just as easily be an inventory number, and if it is handwritten, that is more likely.
Without seeing the picture in person, I obviously can't confirm my suspicions. If your research continues to draw a blank it might be worth showing the picture to someone with some expertise such as an art dealer or an auctioneer.
