The original version of Jammin' Jenna does not have internal wires to help her pose. A second version was produced with internal PVC-coated wires. The second version is approximately .5 inches shorter; her face is wider with more horizontal eye alignment; the fabric design of her belt and shoes is cloth pin-stripe instead of vinyl material; the string attaching her earrings is flesh-toned instead of yellow; her jeans have Velcro fastenings in the legs; there is an extra line of text on the reverse of the tush tag that reads, "& PVC COATED WIRE" and her underpants have more of a bronze metallic color. The second version was also sold with a comb. Sondra noticed that the second version has a "fuller" figure.
