This set of 4 hammered aluminum items will assist you with your next party; the 11 1/2" square tray is a lighter aluminum than the other pieces and does not have a logo. The 11" round tray or shallow (1 3/8" high edge) bowl has "Everlast forged aluminum" with logo and "B 8" on the bottom. The silent butler also has "Everlast forged aluminum" and B 15 on the bottom, has a 5" handle in the shape of bamboo and a lid that flips up to aid in cleaning up--or put some small food items in it for a buffet table. The 8 1/2" round double handled item appears to have been a lid for something, judging by the placement of the bamboo design; it does not have a logo. It could be used as a server (design side down) or place it on a bowl as a lid to keep food hot. All of these pieces are part of the post WWII history of using the left-over aluminum when it was no longer needed for airplanes. I have some other hammered aluminum items and will combine orders for discount and shipping savings, to allow you to set up a party with aluminum that honors history.
