I can see Mama...

 ...standing there on her skinny little legs, with her head bowed over this camera, my brothers and sister and I sitting there frozen, with bright smiles on our faces, until the flash bulb exploded in a burst of light leaving us blinded for a moment.

So I just had to buy it!  I found it at the Oregon Street Antique Mall.

'Member that, Mama?  'Member?  Imagine having to wait for a month to see the photographs!
