Most tears, particularly those alone the fold 
    lines, can be repaired by re-adhering the tear
 
    with the use of non-acid archival tape on the back side of the poster. NOT 
    SCOTCH, MASKING OR ANY OTHER TYPE OF HOUSEHOLD TAPE. 
  We recommend an Archival Document Repair Tape 
    that is released by Lineco. It's easy to handle, non-acidic, can be removed, 
    and almost invisible. You don't normally use that much at a time so one box 
    usually last quite a while.
