respect to other tabs of the other panels as best seen in fig1 so that all tabs are visible at once the indicia 310 on each tab face the inner or forward side 34 of the billfold the total size of the master plate 12 is such as to be completely received within the outlines of the billfold 14 and the tabs 300 are so constructed as not to project beyond the outlines of the master plate 20 when the master plate 20 is looked at in side elevation i have discovered that when the left and right positioning end portions 72 of each panel 50 extend back upon and lap the remainder of the panel a distance of 1 inch that that is sufficient for causing the panels to stay in place during use for that reason each retainer 40 is preferably 1 inch in width as measured lengthwise of the master plate and the total distance from a retainer edge 44 or 46 to the inner end of a respective connector 90 at the line 92 of fig3 is 21 2 inches in effective models the distance between retainer edges 44 and 46 in successful models has been 71 2 inches and the total length.
