I have a quick question. I have some WW2 era stamps, etc that I would like to use on clothing that I might be selling. These are stamps without goverment contract numbers, And for the most part, defunct logos that do not represent anything current (They aren't the Marines logo, etc.) Things like the ww2 ordnance logo, etc. They are also marks that vary greatly (each maker made it somewhat different anyway). So I don't know if the government had any trademarks or copyrights. Is it legal to do this? I was just curious, do companies that emulate military surplus like Buzz Rickson and the Real Mccoys have to obtain permission from the US government to use military logos, stylings, graphics, etc? I'm not asking for in-depth legal advice, just a general opinion. And if there are any lawyers who have experience with this first hand, please PM me. I am more than happy to work something out.
