This Bluefin Tuna saltwater fishing t-shirt design by artist Billy Walsh emphasizes the bold simplicity and speed of a tuna. If you've ever seen or wrestled with one of these beautiful monsters, you will appreciate the design's striking nature. The stylish t-shirt color combination of two shades of blue is a tribute to the "blue" in a bluefin. The Tuna is printed on the front of the shirt and there is a subtle Shark Zen logo on the upper back neck area.
