A poster clamp having a clam-shell clamp having an upper member and a lower member, the upper and lower members rotatable about a common hinge between open and closed positions, and when in the closed position a first clamp arm on the upper member overlaying a first clamp arm on the lower members, and when in the closed position a second clamp arm on the upper member, coplanar with the first clamp arm on the upper member, overlaying a second clamp arm on the lower member, the second clamp arm on the lower member coplanar with the first clamp arm on the lower member, the second clamp arms extending substantially at right angles to the first clamp arms, the first and second clamp arms having longitudinal outside edges, the hinge along the longitudinal outside edges of the first clamp arms, whereby when in the closed position the first and second arms of the upper member are in substantially parallel engagement with the first and second arms of the lower member to thereby releasably frictionally engage a sheet placed between the upper and lower members.
A poster clamp comprising a clam-shell clamp having an upper member and a lower member, said upper and lower members rotatable about a common hinge between open and closed positions, and when in said closed position a first clamp arm on said upper member overlaying a first clamp arm on said lower member, and when in said closed position a second clamp arm on said upper member, coplanar with said first clamp arm on said upper member, overlaying a second clamp arm on said lower member, said second clamp arm on said lower member coplanar with said first clamp arm on said lower member, said second clamp arms extending substantially at right angles to said first clamp arms, said first and second clamp arms having longitudinal outside edges, said hinge along said longitudinal outside edges of said first clamp arms, whereby when in said closed position said first and second arms of said upper member are in substantially parallel engagement with said first and second arms of said lower member to thereby releasably frictionally engage a sheet placed between said upper and lower members.
