This is the same one I am using. I got mine off ebay and had a local sign maker do the logos for it.

thanks guys…do you put your phone number on them…or just your logo…

I have the Logo and number on the front and back on the side just the number.

We use the Autosox.com CabbieXL because of greater printable area . . . and great service so far.

We have our phone number and small graphic on side . . . .and logo and big phone number on l;arge front/back panels. We run the sign across the car with large panels facing front and back.
