Check this out! Love the info. Galen was right... about rubber balls, or 'house balls'. We were wondering if they say they are made with 'safe paint' knowing how toxic it actually was, what did they use before that?! anyway, also thought it interesting that you could get a net bag way back then, full of slags! Does anyone have one that old? this is out of a catalog from. Charles Williams Store, NY. WE figure by the items pictured in the full ad, time frame is approx. 1890 to 1910. Although the rubber balls here are much bigger than the one Tom has, it only goes to reason, that if they made big ones, they would also make small ones. just thought we'd share.
