If you build dioramas, scale kits, models, replicas, diecast, etc. it’s nice to enhance your displays. Signs works real well you can use Speed Limit signs, Construction Zone, Exit Here, Wayside, you can even use Beer and Soda signs, you can use the Vintage or Modern signs depending what era you are trying to display or you can age them yourself (it’s easy to do).
There are all kinds of different signs over at How To Make A Diorama .com and there is also a “Size and Percentage Chart” that you can download for free. This “Size and Percentage Chart” is good because everything is created in 1:24 scale to stay consistent and then you decide what scale you want to print it in, if you want 1:32, 1:48, 1:18, etc. it doesn’t matter you increase or decrease it to whatever scale meets your needs when you go to print the signs.
