Two different sleeves issued over the course of the pressings, the first certainly being the one with a selling price of $1,98 printed on the back (then increasing to $2,49).
The first sleeve had two different kinds of round record label, first orange then yellow, with a new layout; the second sleeve returned to having an orange label. It should be noted that, for some titles, the three kinds of label had different spelling mistakes.
