An answer could be "The title of this picture is 'Man and a Train.'"
You find the main idea of the graph then make the title based on that.
The title depends on whatever variable is plotted along that axis.
Combine the title/descriptions of the x-axis and the y-axis to create a title such as the dependence of (y-axis) on (x-axis) along that basis
it describes the data shown simply in a short phrase

According to the Martin Guitar website the guitar with that serial number was made in 1985.
D28 and D18 are likely references to two models of dreadnought guitars the CF Martin company has put out. D18 being the less expensive of the two...and D28 being a step up with significantly more exotic woods used for the back and sides. the HD28 takes both models a step further by using herringbone purfling around the edge of the guitar.
