1977 Topps Football Oddities

Nikklos

Does anyone know anything about 1977 Topps football cards that look like this? Are cards like these a different issue or variation or just a printing error? Thanks for any insight.

Simply a printing process error that quality control missed. In the four color printing process looks like the red was missing. On the back the statistical information also had a red screen. Unique error, but probably not worth much and vg hofer.
