and further includes two relatively shorter end walls 13 which substantially lie against the two longer parallel walls 14 of the case 10 when the insert is installed in the case the second longitudinally extending wall 15 of the insert does not contact the floor 18 of the attache case thereby providing a tunnel passage 16 which extends the length of the insert the lower edges of walls 12 and 13 rest solidly on the floor 18 of the attache case when the organizer insert 11 is installed therein the tunnel passage 16 is an important aspect of the invention in that it allows legal size and other long documents 19 to be placed in the attache case and to lie flat therein with end portions thereof extending through the tunnel passage 16 and beneath the organizer insert as best shown in fig2 smaller documents 20 such as letters may be placed in the case 10 in the large unobstructed area between the insert 11 and the distant case end wall 21 fig1 in the fabrication of the insert 11 a plurality of top opening depressed compartments 22 23 24 25 are formed the number shape size and depths of these compartments can vary as shown.
