I claim:
A wall molding incorporating releasable clamping
means particularly suitable for easily positioning and
holding sheet material on a wall in spread display such as
pictures, drawings, diagrams, and the like, comprising a
?rst lineal member securable on a wall, a second lineal
member disposed over said ?rst lineal member, spring
means disposed between said members releasably forcing 10

nal trough and said second lineal member having a non
mating tongue having an opening receiving said spring
means and an extending edge rockably lying in said trough;
said tongue and trough providing off-centering means in
conjunction with said spring means to effect biasing said
second lineal member into clamping relationship along
one or the other of its lineal edges on either side of said
tongue center.
