Brazil.

Based on the Brazilian flag combined with the present Brazilian route marker cutout shield.

The existing route marker.

And here is my new design.

Prince Edward Island.

This one is similar to what the province posts now, but with some more colour.

This is the existing route marker. Simple enough. 

This was my first idea. A bit more colour, but no pizzaz. 

Now this is much better! I like it! I like it! I like it!

Plus, it would remind tourists in the summer, winter and spring to return for autumn.

New York, Expressways.

How about these? They are similar to Quebec Autoroutes, but are distinctive, because of the watermark.

New York, Second Series.

These are colorised permutations of the existing black-and-white New York state route marker.

Like the first series, the state routes would adopt the colors of the 1970s NYS license plates and the county route markers would adopt the US FHWA standard county road colors, with two variances: there would be a watermark in a slightly paler blue, and the route number would be in goldfinch yellow, not US FHWA standard Spanish Orange (warning sign Yellow).
