Abstract: A laminar structure, for example an identity card, comprises a photograph and a supported hologram. A moisture-impermeable barrier layer and an adhesive layer are disposed between the hologram and the photograph, so that the photograph can be secured to the hologram while the former is still wet. The supported hologram, the barrier and adhesive layers and the photograph are sandwiched between first and second sheets. The hologram is sufficiently adhered to the photograph that, if an attempt is made to separate the supported hologram from the photograph, fracture will occur within the hologram or between the hologram and its support sheet, so that at least part of the hologram will remain attached to the photograph, so that it is not possible to detach the hologram from the photograph, leaving the hologram attached to the first sheet, and thus substitute a different photograph in the laminar structure.

Abstract: A golf club, particularly a putter, has a unitary body including forward and rearward generally triangular and approximately planar panels merging at their apices with an upright socket adapted to receive a club shank. At their intermediate portions the forward and rearward panels are spaced apart, and at their bases the panels merge with the forward and rearward transverse margins of a ground panel substantially square in plan in a plane normal to the socket axis. The upper face of the ground panel has an upstanding, massive hump. One, or preferably both, of the side margins of the ground panel forms a substantially upright impact face.
