Do you have a big chart about 3 metres in length and 2 metres wide?

At 3m long, it would be circa 3.5x the usual wall chart size (and therefore around 1.1m high). Printing could be done by anyone with a roll fed plan printer capable of printing A0 size, but you'd need a good quality PDF image. I notice that the usual size wall chart is available again from Chapter Two, but you'd need to get it scanned in somewhere and check the copyright.

I think mine is about a metre and a half long, but maybe they also produced larger ones back in the day, possibly in cloth?

I have a pdf file that someone produced using vector graphics - which means that it doesn't lose resolution no matter what size you print it. (From this file I was able to use a low-cost online banner printing service to produce one a couple of metres long. It worked very well.)

If anyone would like a copy, I'm happy to make it available through Tom. The only issue is, I have no idea where I originally downloaded it from. The file has no metadata to indicate who produced it. I would prefer to acknowledge the source -- if that were possible.

At least the content is not under copyright.
