Info on a Robert Lyn Nelson Lithograph?

I came across one titled "Maui Daybreak". It was framed, 26x34 inches and looks to have been signed in silver pen(?) from 1981. It is not numbered and does not have a marine life sketch next to signature. I cant seem to find one like it: its on a thick poster board type material and under the picture it says "Robert L. Nelson" in 1 1/2" gold letters with black outline (very 80's) and to the right side next to it in smaller letters says "MAUI DAYBREAK" and under that "GALLERY HAWAII". Picture link is below
