Perhaps one of the most interesting things an artist or illustrator can do is make something that appears timeless. You're not quite exactly sure in which decade it was created in. These modern vintage pieces have a nostalgic feel to them through the use of colors, typography or imagery but there's an undescribable feeling that it was created in these modern times.
Awhile back I put together a post called 25 Magnificent Modern Day Movie Illustrations. It showed modern day artists recreating movie posters in their own, retro-inspired style. Unlike that post, this one opens the field a little wider, showing you a collection of some of the most beautiful and interesting modern vintage art and illustrations around. Enjoy!
