A dark blue-teal photographic town-and-canal view sits behind large centered lettering. The main title is arranged as three uppercase sans-serif lines, with LUCKY in pink and NUMBER SEVEN in white. The author name is very prominent above it: thin white “Alex” over bold white “SMITH.” A small pink tagline sits at the top, and series copy appears near the bottom.
