Investigation on Illustration

The following adds a little more to a query made some time ago regarding a menu sporting the image of Wilfred Vincent Brooks. Don Grant of The London Sketch Club was kind enough to give some suggestions as to the identity of the artists and their artwork featured on this curious occasion which may, in time, provide the answer to Wilfred's connection.

Don points out that the pictures depicted behind Wilfred by artist John Hassall bear similarity to the work of other artists in the aforementioned London Sketch Club.

Top left has a resemblance with an illustration first printed in The Illustrated London News entitled "Deuced Funny" by Phil May. It apparently shows Melton Prior, a war correspondent, sharing a joke with the Punch cartoonist Alfred Chantrey Corbould.

Below this, two monkeys are depicted with their tails entwined. These are in the manner of Clarence Lawson Wood, also once an illustrator for the Illustrated London News. He is known for his ape and monkey drawings. I've not been able to locate an identical image but this is quite close.

Other proposed illustrators include William Heath Robinson. All pinned up follow this paired 'entre nous' theme.

Gerry was able to provide a photo of his illustration by John Hassall for which we are very grateful. His grandfather had connections with the 'Entre Nous Club Commitee', the role of which still remains a mystery. This picture is shown top middle, above Wilfred's head. Can anyone identify the other illustrators or illustrations?
