Is this a real 1971 Topps cello pack?

....or one of those GAI 'grocery pack' mistakes?

If you believe it's the pack that came inside the blue box, it would be a real cello. The pictures of the pack itself make it impossible to tell the thickness, though most grocery cellos GAI graded said "grocery cello" on the flip as I recall.
