The #210B Facsimile edition in core is the “error” edition with the “golden biscuit” ad on the inside front cover and page #5 of the Green Arrow story mistakenly printed as p5 of the Aquaman story.
They published a corrected version with the original ad on the inside front cover and the correct page in p5 of the Green Arrow story.
This corrected Facsimile needs to be added as #210D
