Coma, punto y seguido
This project* was creatively limited, as the author is himself a graphic designer.
He decided typographies, graphic elements and color palette, and therefore had to work around that.
The book is about a man who falls into a coma and wakes up and has to carry on with his life. The first half of the book is him living his life without knowing he is in a coma and the second half is him waking up and having to deal with missing several milestones in his friends and family's lives.
That's why we use a comma in the first half of the book and a dot for the second half.
Trust me, it makes sense in Spanish.
