Just to get back to this thread and for future reference . . . I've just mounted up another series of photos on to self-adhesive foamboard, as I mentioned earlier, but this time I made the order through a wholesaler instead of the local stockist.
I looked through what they had as stock items and found that the self-adhesive 10mm sheet was available up to 140cmx300cm (55"x118" approx.). The actual mounting will still be a bit stressful (understatement...) if you don't have a roller, and certainly would need at least three people -- at least two handling the print and at least one looking after the print-to-board contact. The glue makes an non-adjustable bond immediately, so practice carefully before you remove the cover sheet from the adhesive! The material is fume-free and very clean in use, so has everything to recommend it over the spray-adhesives which I used for one-offs years ago.
