This invention relates to an artists' portfolio, for the purpose of retaining and transporting sheet material such as prints or photographs, in a manner affording protection during carriage but enabling the contents to be displayed individually when required. The portfolio has two covers 1 and 2 joined at 3 which may be brought into juxtaposition and secured by a slide fastener 5 and flap 6 having a catch 7. The cover 1 includes a spine 10 joined with a support board 12 which may be positioned to engage lugs 13 so as to form an "easel" structure. Transparent folders are secured to the spine 10 by rings 15. In this construction both sides of the transparent folders may be displayed by either lying on support 12 or cover 1. Further the folders depend from the rings when in a normal position of carriage ensuring the contents are always flat in a suspended state.
An improved artists' portfolio comprising two outer covers joined so as to open and close book-fashion to form a case, co-operating closure means on adjacent free sides of each cover characterised in that the side of one cover opposite to the side thereof joined to the other cover includes a spine with securing means for sheet material and a flat rigid support connected to said spine which may be swung from a position lying between the covers when the case is closed to a position in which a free side of the support bears on or near the side of the other cover opposite to the side thereof joined to the one cover, whereby a triangular structure is formed with the sheet material to lie against either said support or the one cover, a closure means for securing together the sides of the covers opposite to the joined sides said closure means comprising a flap on the other cover with a fastening means engageable with means provided on the one cover.
