A collapsible easel for artists and the like to support flexible or rigid drawing surfaces in various modes of operation comprising a composite outer leg unit joined co-axially to a similar composite inner leg unit that are pivotal from a collapsed co-planar position to extended operative positions within quadrant arcs, each having an upper and lower horizontal member and each a pair of parallel main legs which house correspondingly co-extendible auxiliary legs and individually extendible leveling legs which have releasable locking means providing height and leveling adjustment thereto, a stabilizer bar pivotally interconnected to one lower horizontal member extended in perpendicular alignment therefrom slidably and pivotally engaged to the other lower horizontal member having a releasable locking means to support the extended positions of the composite leg units, a translatable counter pivotal structure slidably and pivotally engaged perpendicularly to the upper horizontal member of the composite inner leg unit having a releasable locking means; a media supporting platform structure having an arrangement of receiving members secured to its back surface area to releasable engage the same widthwise or lengthwise to the upper horizontal member of the composite outer leg unit and to the counter pivotal structure by which it is supported and regulated in angular positions as well as in tilting-rotational positions; an optional accessory attachment means to be engageable by adjustable locks longitudinally to either edge of the platform structure and to contain drawing implements and the like therein and to secure and support an elective drawing surface optionally therewith. When the easel is in a collapsed position the composite leg units are co-planar with the counter pivotal structure, the stabilizer bar is vertically disposed adjacent therewith and each are secured thereto by the corresponding receiving members of the platform structure engaged therewith providing a compact transportable and storable unit.
