Don't take our word for it. Try them, and if you are
not more than satisfied, return for full credit. Most music
dealers sell Talking Machines and are making money. Are
you selling Zon-o-phones and Zon-o-phone Records ? We
offer the best inducements to the trade. Send for our dis-
counts. We can make money for you. Our Records are the
best. Why ? The grooves are much finer, thus making our
records play longer than any others of the same size.
Our material is harder and there is no scratching on Zon-
O-phone Records. Order the May list of 10-inch Records
for comparison with any list of 25 records issued by any
other company. If you do not think they are better, return
them and we will refund your money.
