1937: Joke or pleasure
This looks like an odd cartoon. What is wrong with a joke that is also pleasurable?
1937: Snubbed by the hostess
There seems to be an implication that the young guest is having various fiancés all the time. The man in question looks worried by this.
1937: Sad … but true
I have heard this joke before I saw it here. It certainly isn’t a joke for the participants.
1937: Fascist uniform is fancy dress
Communist members of the upper middle class have been depicted here. Here Walter is being teased for his Fascist tendency by the woman in her Columbine outfit.
This is clearly a satirical judgement on Fascism.
1938: A child’s concept of time
Grannie is not pleased. She has taken the trouble to take the child to the Natural History Museum to find that she is supposed to date back to the Ice Age. A small child could easily suppose that time is so flexible.
1938: A delicate enquiry
The butler cannot shirk this awkward mission. He clearly lacks the authority to tell the girl that yes, of course she must wash herself again this morning. If she is to progress to being a lady this is what she will be doing for the rest of her life.
1927: High society snub
I am assuming that the point is that after the divorce she will no longer counts as a relative.
1938: She is rather helpless herself
The pipe smoking husband is wearing a once popular garment called plus fours. It counts as sporting attire. The name is due to the rule that the trousers only came four inches down the leg,
I remember seeing it worn around 1950 but no later.
Separate bedrooms as well. 
1938: Unlucky diner
The cartoon exudes gloom. The waiter is clearly unhappy with his job. The customer appears to be resigned to his fate.
1936: The French!
Words are not necessary in this strip cartoon. In reality the French Customs Officers would certainly be aware of this English sport.
The only civilised countries in this world are those where cricket is played. 
1934: A mixed message
The husband assumes that the woman seated next to him is complaining whereas she is simply making polite conversation. However we can see the wife holding forth in the background. Perhaps the husband feels that his comment was needed.
1938: An independent recommendation
Commissionaires used to be considered to be a necessary adjunct to a cinema. I don’t know when they were no longer needed. The growing number of television sets no doubt is responsible. I think they were usually retired sergeant majors or Chief Petty Officers.
1938: War is round the corner
We know it for a fact, though ‘they’ couldn’t – the war was coming.
So much is clear. But who is speaking and what precisely is the point of this particular joke? Is it the passive man in the armchair or the butch woman with her back to the fire place? My guess he is speaking and telling her that Hitler is not a person to be ‘hailed’. I also think that the point is that even former admirers are coming to the reluctant conclusion that he has to be opposed and only war will remove him.
1938: No earphones
The children have no choice. Their mother appears to be a Wagnerian judging by the portrait on the left.
1939: Masking one’s feelings
We observe true feelings that have been completely masked.
1939: Young man’s lament
Of course, Dad IS living in 1939.
His plus fours signal his retirement. His slender son’s lament makes us wonder what it is that makes him feel so despondent. There’s the forthcoming war, obviously. Otherwise it doesn’t look that bleak for him.
Nothing’s changed - today’s youth also consider themselves badly done to.
Yes, perhaps that young lad in the cartoon was the very first snowflake, decades before the term was even coined!
