In this form of the invention shown in Fig.1? the construction of the interchangeable price card sign is similar to that shown in Fig. 1, except for the provision of a slightly different means for sup-- porting the sign in position upon an articleupon which the sign is being used to indicate its price. In this form of the invention thecontainer IU of the sign is provided with a pointed element having a flattened top end 5i securely soldered to the bottom wall I l of the [container H]. In other respects this form of the invention is identical to the previous forms.
