It's the title of the painting.
Looks like "漓江风光, 己巳年, 晓晗画"
漓江江风光 means the view/scenery of Li River, which is a famous river in Guilin, southwesten China.
己巳年 is a Chinese traditional way of numbering years. For example, 1869,1929,1989,2049 are all numbered as 己巳年.
晓晗 is the author's name.
画 means painted.
So together, it means:
This painting shows the great view of Li River. 晓晗(Xiao Han) painted at the year 1989(or 1929?)
