@oristarA,
Yes. Left to right: Pat Nixon, Richard Nixon, Dwight D Eisenhower, Mamie Eisenhower.
"Ike" was the nickname of Dwight D Eisenhower, US President from 1952 to 1960, and "Dick" is a common shortening of "Richard". Since the picture shows Eisenhower with Richard M Nixon, it is clear to whom this refers.
"Dick" is under "Ike"'s name and vice versa.
The early 1950s style clothes worn by their wives and the text confirm that the item shown is a 1952 Presidential campaign poster. In that campaign the young California senator Nixon was Ike's running mate.
By the way, in your title, both "ike" and "dick" should have been spelled with initial capital letters.
