A device for determining tonal values of a graphic display comprises a mounting support which has a reference pin thereon and a positioning pin spaced away from the reference pin for example a radial line. A plurality of indicator members preferably in the form of wheels are provided and each of them includes a reference pin receiving opening to permit them to be rotatably mounted on a reference pin. In addition they include a plurality of circumferentially arranged defined images or word displays which have distinct characteristics in respect to tone or tint or color. The wheel is rotatable to present any one of defined areas with images or wording in a selected position for example an upright position for viewing. Each wheel also has a positioning pin engaging opening which may be engaged over a positioning pin defined on the support. This gives a selected orientation of one wheel and one or more additional wheels may be superimposed on the one wheel. The additional wheels are similarly oriented in order to provide a combined effect of tone, tint and color for ready viewing and appraisal.
A container for graphic displays, comprising a container base having a top closure wall with a fold groove extending thereacross at a spaced location from one end of said top closure wall and defining a rear closure panel portion on one side of said groove and a front closure panel portion on the opposite side of said groove which is pivoted to said rear closure panel portion, an outer top cover having an inner end pivoted to said container base adjacent the rear end thereof and an opposite outer end, and an easel display support panel having an inner end pivoted to said outer end of said top cover and an outer end adapted to engage in and be propped by said fold groove.
A device for determining tonal values of a graphic display, comprising a reference mounting support having a reference pin thereon, a positioning pin on said support spaced away from said reference pin, and a plurality of indicator members at least one of which is transparent and each having a reference pin receiving opening and being positionable on said pin for rotation thereon, each of said indicator members having a plurality of defined images arranged in separate areas thereon and which are of distinct characteristic in respect to at least one of:
