St Patrick's Day Postcard 1917 Embossed Card - Free ShippingPostcards, back in the day, were a way to greet families and friends.  No matter the occasion, a postcard provided a message.  Sending far away, across town or even next door, a way of communicating, just as we do by phones today.  A forerunner of our text messages today, if you will. 

Here's a St. Patrick's Day postcard from 1917 with a quick sentiment of "Many Happy Returns Of The Day" in written message.  For a penny it was mailed. 

As then, my greeting to you....Many Happy Returns Of The Day.  Have a wonderful St. Patrick's Day!
