Hi,
Just wanted to send a quick update - I checked with the Fedex copy store down the street from me and they are unfortunately not able to copy or scan colour posters of this size. I will research other options.
Note that March / April tend to be fairly rainy / windy in Toronto and I don't feel comfortable transporting these in poor weather (they are extremely fragile). It may be a month or so before I have a solution to scan them and will update all with the options once available.
- Mike.
