Side note... often a lot of the scrolls on ebay that are for sale are not actual real art. They
are just reproductions that have been machine printed on scrolls, also... just like mass produced Bonsai, there are literally businesses that have hundreds of employees sitting in a room day in and day out mass producing hand painted scrolls. So, yes they are hand painted, but the quality of the art is one the level of a big box store ginseng ficus. Unless the scroll is battered and worn, most anything of any quality is going to cost some money, as it should. A five dollar scroll is worth five dollars.
I could be wrong, but I am pretty certain that the image on the scroll you have pictured is not an original. Looks very familiar... Also, as has been stated
before, this is not a Japanese Scroll... The scene depicts the Huangshan Mountain range in China, birthplace of Bonsai... But, it is most definitely Chinese.
