Hello,
Here's a nice little piece of L&L memorabilia...I got this from Ryland at the 2011 Chicago Vintage Show.
1933 Ludwig & Ludwig gold/white enamel lapel pin
I say 1933 as the text is from a 1933 Ludwig Drummer magazine...I'm going to research and see if this is mentioned in an earlier Ludwig Drummer.
Enjoy!
