Hi guys, This large, 55"x 26" poster came from a local BMW dealer. It looks to me like something they had made up locally as the writing is in English. It says 1975 on it but of course it will be pretty similar for many other Si years. It's printed on heavy poster paper stock and finished in a sheen that prevents it from getting too grungy but make no mistake, it's been in shop for decades. Easy on the eyes when you're troubleshooting the circuits. Free to the first poster here for the cost of postage in a sturdy cardboard tube. I ran a price check from Milwaukee to LA and it came out at $13 for USPS Priority.
