HUGE credit to @mac84tv for the source image!
I tried to find any 2400c poster or ad, but couldn't! I looked EVERYWHERE!
So, I did the sensible thing and reached out to everyone's favourite Macintosh Archivist & Image Writer Enthusiast! Within minutes, he located a brochure (gifted to him in Japan 9 years ago) AND scanned it in high-res. THANK YOU, you're the best!!
