Scooter Jawa 50 c.c. (Model 555)
You will observe from the price list that this occasion marks the introduction of a new Jawa model for the 1959 season. We take pleasure in attaching an introductory leaflet of this addition to the Jawa range. You will observe that the new scooter is most comprehensively equipped and most competitively priced. In fact we believe it to be the lowest priced scooter on the market today. Further supplies of leaflets are available on request, and we look forward to your valued order for this machine, supplies of which are available from stock at the moment.
The price at the time was £87 3s 0d.
