end of each piece 48 has an inwardly pointing bevelled flange 52 which is of similar extent to the intermediate flange 50 between these two large flanges 50 52 there is a thinner and shorter flange 54 each display member is dimensioned so that it can embrace a pair of tongues 16 of a bracket 12 the different display members 40 42 44 differ in the width of their bases 46 the smallest member 40 is dimensioned so as to embrace an adjacent pair of widely spaced tongues 16 the next largest member 42 also shown in fig5 is of twice the size and the largest 44 is of three times the size of course still larger display members could be used in each case the arm pieces 48 extend beyond closely spaced tongues 16 it can be seen that the dimensions are such that when there are a pair of display members 48 occupying adjacent sites their adjacent arm pieces 48 are in contact as shown in fig5 a display member can be fitted to the support 10 so that tongues 16 thereof engage either between the intermediate flange 50 and the base 46 as with the member 42 39 at the left in fig5 or between the two flanges 50 52 as with the member 42 at the right in fig5 this will.
