The term "Bread Box", is a play on words, using "bread" in the American/English slang, referring to money, (ie; "That's a lot of bread."). The logo should be indicative of this.
Bread Box Industries, and most of its subsidiary companies, literally, just sell "cash money". We are not a bank, a foreign exchange, or a check cashing operation, but merely a cash retail outlet, (basically..).
We are not looking for slices of bread, or anything to indicate we have anything to do with the baked loaf known as "bread", or the box, in which it is kept, (aka "bread box").
We will also be needing more logos, for the subsidiaries, and as this seems to be going so well, I may see how it goes with a web site or two.
