Few months ago I was spending my afterwork hours on nautical themed ex-libris for my grandfather who is big enthusiast of sailing. I have took inspiration of various nostalgic ink ex-libris and oil paints of 17th century galleons. I also added few palm trees to create a little bit of tropical vibe requested by grandfather. Whole illustration is rather simple and single colored without any color transition because it is base for rubber stamp engraving. 

Just for fun I've created few mood mockup's with help of tweaked and modified stock images.
