International Association of Machinists and Aerospace Workers
I used to be a member of Local 2597 International Association of Machinists and Aerospace Workers (IAM).
I did this IAM vector logo for a t-shirt deal I had going with them. Feel free to download it if you need it. I found a high rez jpg and cut it out from there, layered it out and saved it in all formats.
That pic you see to the left is 1800px png – The following zip file though has everything you could want. .ai .eps .svg .pdf .png
