Old Fashioned 1940's Tea Party Loaf

My Grandmother loved to entertain and made any excuse to have a party.  This was a family favorite that was made for every little event.  It always looked special and was so simple to make!
Party Sandwich Loaf
The Ingredients.
1 loaf very fresh unsliced sandwich bread
3 different but compatible sandwich fillings: use 1 cup of each (ham salad, chicken salad, tuna salad, pickle salad, egg salad or olive nut spread)
2 (8-oz) packages cream cheese, softened
2 to 3 tablespoons of milk
Note: Use unsliced bread, glutton free, white or wheat, or both, layering slices alternately, ribbon fashion. Crusts should be removed from all 4 sides of the loaf. Slice the bread lengthwise, evenly, to make 4 long layers
The Directions.
Butter, with real butter, all sides of bread that will be touching a filling. On a serving platter or tray, place bottom slice and spread generously with filling, cover with next slice of bread. Spread second layer of bread with filling and cover 
with next slice of bread. Spread third layer of bread with filling, cover with top slice of bread. ¨
Frosting:
In a separate bowl, beat cream cheese until fluffy. Add milk, 1 tablespoon at a time, until cream cheese is the consistency of creamy cake frosting. "Frost" sandwich loaf using the back of a spoon. You can decorate with more cream cheese in pastry bags, either tinted or plain. Chill until about 20 minutes before serving.  Garnish with parsley, cucumber slices, radish roses, carrot curls, whatever fits the occasion.  Mom always would make little tomato roses or radish roses with olives and parsley leaves. 
To serve, slice with serrated knife and place slice on a plate.  We always found an electric knife worked great.
*Best frosted the day of the event to prevent the frosting from drying out.
