摘要：A pair of elongated upper and lower horizontal frame bars are providedtogether with a pair of upstanding opposite side frame bars. The upstanding oppositeside frame bars extend between and loosely end abutting the lower and upper surfacesof the corresponding end portions of the upper and lower frame bars and all of the barsinclude inner and outer sides with the inner sides having coplanar grooves formed thereinand extending longitudinally thereof for receiving the corresponding marginal edges of aposter bound on its edges by the frame bars and with the poster member forming akeying element engaged in the slot of each frame bar and thus keying the bars together,each against lateral displacement relative to the other frame bars transversely of theplane of the associated poster. The opposite end portions of the upper and lower framebars project outwardly of the outer sides of the upper and lower ends of the

corresponding side frame bars and the end portions include upstanding bores formedtherethrough immediately outwardly of the outer surfaces of the corresponding sideframe bars. The opposite end of an elongated flexible tension member are threadeddownwardly through the bores in the ends of the upper frame bar and also downwardlythrough the bores in the ends of the lower frame bar and are knotted through the lastmentioned bores with the midportion of the tension member being upwardly

displaceable from the upper frame bar and engageable with a suitable suspensionmember.
