Abstract
A drawing toy having a housing and a web of material upon which a child can draw, color or mark. The housing includes a generally cylindrically shaped shell formed of two generally semi-cylindrical halfs. A hollow spindle having the web of material wound thereon it is located in the shell in substantial coaxial relationship with one end of the spindle projecting from one end of the cylindrical shell. A cap is removably attached to the projecting end of the spindle so that as the cap is turned, the spindle is caused to rotate about the longitudinal axes of the shell to unwind the web from or rewind the web on the spindle. A slot is formed in the shell through which the web of material moves as the web is unwound and re-wound on the spindle.
