A 
                  tear occurs when a part of the poster is separated from the 
                  remainder of the poster. 
                CAUSES
                Most 
                  tears occur in the area of the fold lines. When posters have 
                  been folded and unfolded a number of times, pressure is placed 
                  on the fold lines and this can sometimes lead to separations 
                  or tears. Tears can also be the result of mishandling or poor 
                  storage.
                IMPACT 
                  ON POSTER VALUE
                The 
                  location and size of the tears will determine what impact it 
                  will have on the overall value of the poster. If the tears are 
                  on the border of the poster, they will not impact the value. 
                  If the tear affects the artwork of the poster, the value of 
                  the poster will be decreased. 
                  
                REPAIRS
                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. For larger or more problematic 
                  tears, seek a good restorer.
