This issue was mistakenly printed by rotary press, this made it useless for the intended customer who required flat plate printed sheets to create coil stamps. The difference being the amount of space between the stamps. Rather than assign these stamps to waste the Post Office sold them through their Washington DC philatelic agency.
Because these sheets were intended to be cut into four panes there was a cross placed in the center of the sheet with matching outside lines at the edges.
These center cross gutter blocks are desirable and command prices in the range of $60 - $70 range for never hinged blocks of four.
The source for the design was this photograph of Warren Harding.
