More Old Clay Marbles! Set One cast iron boat I find this unusual square

I find this unusual square presumably slab-formed bowl super interesting and very lovely

and indeed I'd love to build a whole dressing room around it

but I am not really certain how old this piece is

On the right side of this piece in black is hand-written text

The cover of the portfolio is fairly torn as are the paper backings for a few of the tipped in prints

More Old Clay Marbles! Set One cast iron boat I find this unusual squareI'm not over my obsession with old clay marbles, and have just added four new (old) sets to the shop. I really love how each batch I've found has a different personality, and, like rocks, each marble is unique. Just so lovely. About 50 marbles exactly as shown. They are making pretty dramatic shadows against this white plate! These average about 1 2" in diameter, some a little bigger, some a little smaller. I've tried to weed out any with much damage,
