This package includes a strong, steel freestanding frame with 25 poster panels in the top displayer and 10 poster sleeves in the bottom browser. Additional panels/sleeves are available seperately . The panels and sleeves measure 22″ x 30″ but please note that these are external dimensions and 1″ greater, on each of the four sides, than the poster which they will hold. The panels are in one piece, acid free and ant-static. They are edged in strong fabric which comes in a choice of colours. The corners are reinforced and the clear plastic screen has a seperator within it to allow two posters to be displayed back to back. Units can be made to measure.
