Creating Modern Road Signs in 1/35

They are pretty easy to make yourself.  Find a picture of the sign off the internet then copy and paste it into a graphics program; I like to use PowerPoint.  Resize it to what you need and print it off on regular paper.  Cut out and glue to a piece of 0.020 sheet styrene with the back painted silver or whatever color the country you are depicting uses.  Plastruct and Evergreen make structural shapes in plastic, such as I-beams and girder section that can be used for the support for the sign.

There are kits of signs available commercially, too.

I just did a websearch on "1/35 scale road signs".  While that included a lot of hits for WW II-era signs, this search page from Scalemates was also returned:

There are entries in that list for Iraqi road signs, as well as other sets.

MiniArt is also shown, and it would be worth it to have a look at their website, because I think they've also produced sets.  They have figures and diorama accessories for the modern Middle East, so I would not be surprised if they also have sets of road signs.

Verlinden may have made some, too, and the German company Peddinghaus.  I'd have a look on eBay for those.

Hope that helps!
