I got the photo from here:
“From the 16th-18th centuries both alphabet books and hornbooks usually were associated with religious and moral instruction. The best-selling alphabet book of the 16th century, for example, was The ABC with the catechisme (1549).
Most early alphabet books resembled hornbooks, as the alphabet was most often printed in the form of a table. This began to change with the publication of the first illustrated English-language alphabet book, John Hart’s A methode, or comfortable beginning for all unlearned... (1570).”

Could be that was one of the 18th century ones, though, it matters not, of course.
You've misinterpreted what's illustrating what. You're looking at an illustration of the previous paragraph, which explains about Battledores:
...use of the hornbook declined rapidly during the late eighteenth century when cheap, mass-produced, illustrated booklets became more readily available. These booklets, usually a single sheet of card folded in three, were known as battledores.... Originally cardboard battledores were printed on just one side and were varnished on the text side to protect them. Later, however, they began to have text on both sides. The prayers included in the hornbook were often omitted and a variety of other texts, such as short poems, were included instead. Their modest price, charming illustrations and more entertaining texts all contributed to their popularity and to the decline of the hornbook....![](http://privatelibrary.typepad.com/.a/6a01156f7ea6f7970b013485979e9f970c-pi)
Of particular relevance in that page, however, is the statement, "Also known as abécédaires, ABCs (and similar variations), alphabet books have introduced children to their native language since at least the 16th century." Prior to the 16th century, such grammar and spelling books did not exist
BECAUSE THERE WAS NO GRAMMAR STANDARDIZATION TO TEACH PRIOR TO THE WYCLIFFE BIBLE.
