Lotta comics of that era were good for a slight smile at best. More for the novelty of the idea than the humor of the execution.
Hagar was an example of that genre. And I liked Hagar back then. It was really just Fred Flintstone drawn as a Viking. Good hearted but generally inept and both took his wife for granted and was in turn outsmarted and henpecked by her.
Wow, that’s a terrible interface on Google to view on a phone. I could not figure out how to zoom in on sections of the page to actually read anything. Best I could do was download individual 256x256 pixel segments from it.
I got Hagar as 3 segments and did an AI upscale on them.
Riiiiiight. Those are definitely nothing more than fish scales!
So they WERE chunks of food! Hagar, you’re horrible!
Thanks for posting it, OP was really close.
There is a “zoom in” button, but it’s hard to find.
Clicking on a headline is easier. The interface hardly ever recognizes comic strip titles as headlines so you typically have to go for the nearest recognized one.
I don’t know if I’d consider an entire year off as 98% accurate 
but glad you found it!
I’m glad we got a link to The Comics Curmudgeon… but watch out! I just spent three hours catching up on that rarity: an entertaining Mary Worth storyline.
I said it appeared prior to 15 June 1975 because I remember citing it that week, but not the specific day. I also knew I had seen it earlier, but not by how much.
Being one year off after more than 50 is pretty damned good, I think.
When looking at history on the geological scale, you are absolutely correct that a year is “not very long before”.
The “Mermaid” shtik was used in Futurama, too. I guess interspecies sex is not meant to be. 
Nearing the age of 71, I’m proud to have remembered it at all! 
Your recollection of the actual substance of the comic was pretty spot-on too.
They loved each other but weren’t in love.
A pretty girl complimenting you on how nice your beard looks sticks in your mind too!
