Stop in for a cup of coffee

I was looking at pics this morning. This was on a 67 GTX Hemi car.
Whats up with the sideways T punched in the left fender tag??
Did they really put a Hemi Engine tag on them (right tag) or is that someone's humor??

Might be real. Barry would know.
Seen 2nd tags discussed in moparts restoration forum.
