A few years ago, it was possible to buy T-shirts with almost any RR logo or herald ever made, new or old--C&S, AT&SF, Great Northern, Boston & Albany, Pacific Great Eastern, RGS, WP&Y, Belfast & Moosehead Lake--you name it.
Recently I tried to find such shirts but without success. I've looked through magazines and on the internet, but I can't find anything with a logo or herald--just photos of locomotives and the like.
Are logos now off-limits? Trademark infringement and all that? Or am I looking in the wrong place?
Thanks for any help.
