Mickey and Minnie with Pluto and Morty and Ferdie

After posting this on a few Disney forums, I think this is Mickey and Minnie, with Pluto and Mickey's nephews Morty and Ferdie in the bull costume. It looks like there could be one hiding in the back of the costume? maybe?  Well, whoever it is, I hope the picnic was fun  :D

The back reads:

Mickey's Nephews:

Morty and Ferdie Fieldmouse are Mickey Mouse's nephews. They first appeared in Floyd Gottfredson's Mickey Mouse Sunday comic strip continuity titled Mickey's Nephews (1932). Since then they have appeared in lots of comic strips and comic book stories starring Mickey Mouse and Pluto.

In pre-World War II Mickey children's books (not comics) produced by the Disney studio, the nephews were usually called Morty and Monty rather than Morty and Ferdie. Very early books contain three or more nephews with various names, including Maisie and Marmaduke. Morty's name, short for Mortimer, is possibly in reference to the originally planned name for Mickey, Mortimer Mouse and Ferdie (sometimes misspelled "Ferdy") is short for "Ferdinand."
