Vintage Lucite Vanity Mirror

Nice, compact table-top / vanity mirror circa 1970s, USA. The mechanism in the back suggests that the mirror is fully adjustable, but it can only be slightly adjusted upward and downward (not side to side). Signature present to the back of the mirror itself (doubtful that this is any artist’s signature; likely signed by a previous owner).
There are a few thin, black streaks to the glass itself, as pictured, along with some dings / crazing to the base in the back and some splitting to the lucite on the backside just behind the adjustment. Otherwise, in good, vintage condition.
