A folded sheet article (20) comprises a sheet (22) of material having mutually transverse sets of concertina folds (24, 26) and two diagonally opposite stiff portions (28, 30) at respective corner segments (32, 34) of the sheet (as disclosed in prior British Patent Specification 2173448 B) and has a pocket (40) at at least one of said segments (32, 34). Pocket (40) may be formed separately, may comprise said stiff portion (28), which may be folded back onto itself to form said pocket (40), or may (alone or together with said portion (28), be formed from said sheet (22). The stiffening may be provided by a removable card (58) in pocket (40). Such card (58) may bear coded information (60) related to information (62) borne by sheet (22). Pocket (40) may have means (64) to retard egress of a card (58). Sheet (22) may have pockets (40, 41) on either side, or pocket (40) may have sheets (22, 23) (with stiffening (30, 31)) on either side and then be provided with differential gripping means (66) along the edges to enable opening selectively of the sheets (22 or 23). In a particular method of manufacture, sheet material (70) is glued at the sides on both faces and at one end with glue strips (72 to 80), then folded over stiff portion (28) to form pocket (40), and this is then placed onto said sheet (22) to attach thereto.
