Early vtg Halloween round TAlly Card Witch on Broom Black Cat HBC artist RARE

The initials on this tally card are actually HBG, with the G standing for Griggs. Nothing is known about H.B. Griggs, not even whether the artist was male or female. However, the artist's work is quirky and widely collected. This very same tally is shown on page 219. As an aside, the tally shown here is not stained. It appears to be in perfect condition.  

09/22 Update: And it fetched a strong $53.00!
