Hi Christian, no need to get in contact. I'm here!
I am thankful for your consideration in getting permission first. I do photography on the side and am very well aware of copyright infringement in that industry.
You can guess in the photo who the world's biggest model railroader that Blazeman is referring to. I wished I had gotten a picture with him to show the size different (hint: look in the back). Oh well, there's next year.
