ACDelco A212CW Air filter Application Question

[clm69z28]

I have had this filter in my shop for over thirteen years at this point, and I actually forgot that I had it. After doing a little research, the mesh and color of the filter material suggest that it is for a 65-69 Corvette, but the silk screen lettering seems to be a little different than I would expect. The box that it was in looks like it is for early 70's GM cars, but I am not sure that it is the right one. Can anybody give me any clarification as to the application and maybe value??
