I guess it will take a long time for the subject to get old:  this particular piece of pulp art which appeared on the cover of a short-lived pulp magazine called Uncanny Tales (1939 – 1940) has an unusual appeal, in part because of how explicitly it uses structural elements to make implied nudity possible, but more (for me, anyway) of the “OMG what is happening to me” expression on the face of the model.

Found in this post (with more tube girls) at the very cool blog It’s Dark in the Dark, which has lots of art relevant to thaumatophiles.
