ABSTRACT:
A central shaft supports sets of two laterally projecting parallel limbs. Preferably, four sets of limbs project in 90.degree. relationship. Each limb is serrated to provide a plurality of correspondingly placed card holding notches. Thus, greeting cards may be placed, one to a set of notches, and thereby removably hold in an upright position for viewing and/or removal and return.
In addition, the central shaft is provided in interlockable add-on sets, with similar branches as those of the set below. Thus the tree "grows" as more cards arrive, and by supplying each added shaft with shorter limbs than those below, a simulated tree configuration takes form.
