I love this first sign. It is so 50's. I'm not big into the 50's diner look, but this is a great look for a sign. (Even though part of it looks like it does light up. I didn't see it when it was lit.)
The second sign that caught my eye is the painted on on the brick pointing at a gift shops real sign and door. I love that it's fading away and that it's right on the brick. It makes it look old even if it's not.
These are both in the touristy section of Boston, MA.
