Just like now, billboards were popular in the Old West.
The difference is, they would put them IN the road.
Looking at photos of Old West boomtowns, the roads were a mass of signs from various entrepeurial hopefuls.
Some frames had multiple signs, whether from the same or different businesses.
For mine, the frames are made from stripwood, the signs from a sturdy cardboard. The signs are printed on my computer.
They are based on strips of 1" steel strapping culled from trash bins. Plastic would do as well, but the steel makes them more stable.
'Kellas' Quality Pianting' is sort-of copied from a period original: The name has been changed, but the spelling error is on the original.
The Hardware sign is copied from a period original.
The brush on the left is made from pieces pulled from greenery purchased at Michael's Crafts.
The base of the tufts are heated & flattened, and then covered with a slurry of sand & white glue, allowed to dry on a piece of smooth plastic. When dry, the piece just pops off.
The base is heavy, resists warping, and looks rather more organic than most bases.
The bush on the right is made from an irregularly-shaped piece of sponge, glued onto a number of stems made from wire embedded in putty on a plastic base.
