Again, I do not know how this got past the editors, but you would think that the mother, at least, would have seen to it that her children were wearing cotton briefs that were not worn down to the point of being as flimsy as nylon; especially in the area of the front panel of the boys' briefs which is usually double thickness. That's either really cheap underwear or stuff that has seen a lot of bleaching. The boy holding the dog might be wearing Munsingwear Kangaroo briefs from that horizontal band where Jockeys would have the vertical bands. I am still amazed that I did not notice this in the ad when I first saw it as a teen. Are we sure that some Photo Shop (dare I say the word) software was not used to enhance this?
