That would have been for a brief period during the 68 model year, after the embossing changed, but before the silk screen was added.
Large embossed font lasted until AT LEAST 8/1967.
The earliest box date I have for a silk screened filter (which has the small embossed letters and silk screen together) is 3/9/1968.
So the small font without silk screen should fall some time between those dates. (Of course, the window could be shorter than that, but should not be longer than that.)
