Looks like 268 individual entries. Some are non-canonical ideas of my own for my personal BR projects, some might be simple color variations, some are just real-world logos that (may have) appeared in BR1. Some are even from Ridleygrams and Syd Mead concept art.
Nice graphics! How do I get higher resolution ones? I am making an LED matrix Walk/Don’t Walk sign. I also want to do a parking meter sign.
