I am not only interested in vintage design, architecture, lounge music and stewardesses but also graphic design and typography seeing I majored in it in college and nowadays what I make a living from.
One thing that caught my attention lately are those old handwritten posters and placates that were found in major stores and outlets. Handwritten of course, they were in their own way a work of art. Done correctly they would both look elegant and selling.
Of course, the effect would be the opposite if they were done the wrong way. Here are a couple of nice examples taken from a book about how to learn the quick lettering technique used for signs and billboards. Now grab your pens and start practicing.
