Business Notes TOYS

Collecting baseball cards was once every parent's idea of a nice quiet hobby. The only noise it inspired was the popping of bubble gum. But this month LJN Toys will introduce baseball cards that produce their own chatter when inserted into a battery-operated player called Sportstalk. On tiny vinyl records that have been laminated on the back of each baseball card, players from Hank Aaron to Los Angeles Dodger Kirk Gibson reminisce for some two minutes apiece about their famous moments on the field. The retail price for the machine with four cards will be $28; additional four-card packs will sell for $5. The toymaker has already received 400,000 orders for Sportstalk from such retailers as Toys "R" Us and Child World.
