In a small bowl, mix together the ground ham, 1/2 cup of salad dressing, 3 tablespoons of relish, and onion. Set aside in the refrigerator.
In another bowl, mix together the ground bologna, 3 tablespoons of relish, and 1/2 cup of salad dressing. Set aside in the refrigerator.
In a third bowl, stir together 1 package of cream cheese, walnuts, green olives, and 2 tablespoons of milk. Set aside in the refrigerator.
In a fourth bowl, mix together the Cheddar cheese, 1 package of cream cheese, 3 tablespoons of salad dressing, onion salt, garlic salt, and celery salt. Set aside in the refrigerator.
Spread the ham spread onto the bottom slice of bread, then top with another slice. Cover the next slice with bologna spread, and top with another slice. Spread the next slice with the nut spread, and then top with another slice of bread. Top this slice with the Cheddar cheese spread. Top with one more slice of the bread. Smooth the sides with a large spatula or knife, and refrigerate for about 30 minutes before 'frosting' to make it easier.
Mix together the 2 remaining packages of cream cheese, and enough milk to make it spreadable. Frost the sides of the loaf first, then the top. Decorate with sweet pickles and pimentos to your liking.
