Since I share vintage postcards all the time I'm guessing that I have already posted this one. Oh well. I am sure you will be getting many duplicates over time.
If you are interested in the origins of the phrase Erin go Bragh then click HERE. For all I know, I have probably already shared that as well. I get so confused!
Along those same lines - my advice for any person starting a blog - be SURE to use tags correctly and smartly when posting from the very beginning. It will help so much in finding things in the future! I wish so badly that i had done that.
