It's 1939 and I'm looking at greeting cards. Christmas greeting cards were perhaps the most popular. During this time there were a lot of massed produced cards available and often sold in boxed sets. However, a lot of articles were still written in publications describing how to make your own greeting cards.
In this day and age we take electronic-mail for granted but exhibits back in 1939 was also sending voice mail too.
Today, it's easy to reproduce a photo and have it printed on a card and it may seem a modern idea, but there were articles to show you helpful guidelines to prepare your photos for greeting cards.
I hope everyone is having a good day or evening where ever you are.
