They are from photographic bases, and as such have varying clarity and lighting.
There are duplicates of some signs within this package, and crossing over to other packages. All duplicates are due to either adding a higher clarity version later, offering a different sign style, or offering a different level of wear and tear.
The signs are Modify/Copy/No Transfer, so feel free to improve upon them and rework them. You may want a darker hue or to colorize them, or maybe take them apart and reassemble them, to add a directional arrow sign to another sign for example.
There are only a couple of low-clarity signs that were mainly included for the sake of finishing off a texture map. The majority are of decent clarity and sharpness. With the exception of the sign posts and sand bags, the textures in this series were "mapped" into 10 512x512 textures for faster client loading when many of the signs are in use in the same area.
The signs are done in full prim, ranging from 2 to 15 prims each. Most of the signs are 2 prims. "Full prim" basically means as opposed to 2D or a paper-like sign cut-out that loses realism as you walk around it. Every sign in the series has perceivable depth. You may even want to tilt them or make them crooked to make this more obvious. A few special signs are also included in full 3-D, such as full-size barricades, saw horse barricades, and temporary construction signs with sandbag weights.
