Vintage Glass Hand Painted Halloween Jack o Lantern, VGC

These cold-painted glass JOLs are not particularly rare, but what sets this one apart is the condition of the paint. Made in the teens and into the early 1920s, these typically have severely deteriorated paint. Often they are cracked and missing the threaded top. This seems to be one of the nicest examples I've seen for some time. I think a price up to $200 is reasonable. 

03/21 Update: Someone snagged themselves a deal, picking this up for a relative song at $154.63.
