I bought 8 of them on clearance from the now-defunct Architects of War a few years ago. They are Woodbine Miniatures made by Gripping Beast and listed as 'Scary Scarecrows' in their catalog. Woodbine has a small range and include several other packs inspired by the aforementioned Doctor Who stories. There are 4 different poses.
The last 4 are 'Corn Dolls' made by Crooked Dice. These come as 2 different bodies, with separate arms allowing for more poses.
I painted them all at once in 2014 or 2015, using various shades of brown paint. The straw was painted with Iron Wind Dun and highlighted with Musket Miniatures New Thatch. They painted up very quickly.
The red group of Woodbine scarecrows, so called because they all have red neck scarves. They have some nice details, with random tears in their clothing and straw sticking out.
The blue group of Woodbine horrors shambles forward.
These are the Crooked Dice corn dolls. They have a bit more detail than the Woodbine ones, and the separate arms allow for more variation.
The entire horde approaches. Stay out of the fields!
