City Gent by Monster Riot. I love these illustrations in pastel shades which always tell a deeper story than what you would get from the first look. the red gives accent to the majorly blue colored illustration and brings the focus to tiny details.
This birth announcement was letterpress printed on Crane Lettra Cotton Paper by Gilah Press. The original link shows several pictures of how the card was printed. The letterpress is deep here, and literally adds another dimension to this project.
