I take it back. There are actually folk in gainful employment. Well,
employment anyway.
Many thanks for the help I have received, which has been passed on to the
iron wielder. As follows for any interested parties:
Roll them the other way in a big roll, tie with string, then gradually roll
them tighter and tighter over a long period. Flattening them with a sheet
of glass is good.
The most successful method would be to relax the maps using capillary
matting and gortex membrane but they would still require being placed under
boards and weights.
Gently flatten them by keeping them flat under weights for 2 months or so if
there is no access to relaxation techniques - ie gentle steam treatment
followed by weight treatment - careful of any soluable inks.
Happy Christmas!
