One of my pet peeves is bumper stickers with letters to small to read.
So a Mustache and

across the bottom.
Maybe a dollar sign on each side of the mustache, just to peak interest.
$ ~^~ $
I don't know how else to say FI in short bumper sticker lingo.
I had a 100 bumper stickers made about a lie a president made.
I think it cost about $0.80 ea and I sold them for $1.50, sold enough
to get my money back, still have about 30, but I stopped presenting them,
so no sales.
btw. I didn't put any on my car, just not something I do.
