Card #1 - forbidden toad love

(circa 1933 - signed on back "from loving cousins Sybil and Donny")

I get the whole "Oscar Wilde is a toad" thing they have going on here, although below the waistcoat he seems a little more Rudy from Fat Albert.  I must however take issue with the lady toad in the backless evening gown.  I am not sure that is the best fashion choice if you are entirely covered in warts.  Also can anyone shed some light on the yellow round object behind what would be the ear area?  It looks like a hubcap, although amphibians do have the ability to mutate more so than other critters; it could be a nipple... a human one.
