Well, two intrepid web surfers, constantly scouring every source, stumbled across the same picture.
The only thing I know about Lydia is somebody thought to take her picture, and tag it with her name. As far as I know, she is not related to that other Lydia:
Oh Lydia, oh Lydia, say, have you met Lydia?
Lydia The Tattooed Lady.
She has eyes that folks adore so,
and a torso even more so.

Oh Lydia The Queen of Tattoo.
On her back is The Battle of Waterloo.
Beside it, The Wreck of the Hesperus too.
And proudly above waves the red, white, and blue.

La-la-la...la-la-la.

if you step up and tell her where.

La-la-la...la-la-la.
Oh Lydia, oh Lydia, say, have you met Lydia?
Lydia The Tattooed Lady.
When her muscles start relaxin',
up the hill comes Andrew Jackson.
Lydia, oh Lydia, that encyclo-pidia.
Oh Lydia The Queen of them all.
For two bits she will do a mazurka in jazz,
with a view of Niagara that nobody has.
And on a clear day you can see Alcatraz.
You can learn a lot from Lydia!
La-la-la...la-la-la.
La-la-la...la-la-la.

Oh Lydia The Champ of them all.
She once swept an Admiral clear off his feet.
The ships on her hips made his heart skip a beat.

They said Lydia...
We said Lydia, la, la!
