Hi thanks for looking at my item What you are looking at is a VINTAGE NY Yankees pin back button.Own a part of Yankee History! I do not know the exact age of it but I found it in an apartment I moved into in the mid 80's It's at least 30 years old! It's a little over3 1/2" in diameter.Please super size the picture to see the "AGE SPOTS" Please if you have questions feel free to e mail me I will get back to you within 24 hours. I know I do not have a lot of feedback but you have to start somewhere and with E bay that's at the bottom LOL. I will ship fast and good packing since I have been a buyer I know what it's like not to get your item! Thanks again for looking!
