More men in underwear!
In what looks like a submarine or a battleship, one man wearing Reis Scandals wants to show off his underpants, and now he has found a friend who will look at them. They have a drink together: "I propose a toast! To the scandalous man in the Reis panties, who likes to show them to other men! Long live the scandal!"

The next one is from Munsingwear, with its thinly-veiled homo-friendly situations. This one is titled, "Boy, someone ought to stuff you!", which can also mean, "Boy, I'd like to fuck you!" I guess the man on the right is so alluring, that the man on the left has lost his good manners. In any case, later that night, someone got stuffed.
Dad and Son have come to a baseball game, just wearing their underwear. Wow! What a wonderful world it would be if such things really happened!
In the same "sports theme", we have Dad and Son riding a giant football! I won't try to find the sexual symbolism here, because this picture is too darn wacky!
Here's a nice little picture I just love. The French translates into "Wear the underwear". Don't eat it, use it to mop up that spilled coffee, or use it as a doily. WEAR IT.
Here's a photograph of a father and son. Son is wearing tighty-whities, while unfortunately, Dad is not. Santa looks on, approvingly.
Once again, Mom is not home, so Dad and Junior are playing around the house in their underpants. They're getting Fifi the poodle ready for the dog show. Dad takes pride in his "artistic" expression, and Junior is very gung-ho about the whole thing.
Munsingwear is back, this time with two baseball players. "Inside stuff", in this case means "A man gets something stuffed inside of him". More delightfully naughty thinly-veiled homo-eroticism!
Here's an interesting one with some dads in underwear. Notice how all the crotches are flat as pancakes. Super un-natural.
And what would this blog be without one more Dad and Son picture? Here it is. But it's quite shocking! Not the picture, but the prices. I can't believe underwear was EVER that cheap.
