By now, we’ve all been schooled in the revolutionary ways of stereophonic sound (Part 1, Part 2, Part 3), but there have been significant advances since mid-March that will set the standard in audio technology. Ladies and Gentlemen, stereophonic sound is now available in the color PURPLE! That’s right! At no additional cost to you, the color purple has been integrated into the RCA Victor demonstration insert. Discount blue RCA Victor stereophonic sound demonstration inserts are currently on sale to make room for this year’s fall fashion purple extravaganza. With the holidays coming up, why not give the gift of blue, or if you’re one of the lucky ones whose ship has come in, why not spring for the new purple model? Discounts on the discontinued blue will be applied at the register.
