Introduced in 1908. Discontinued in 1910. This is the rarest of the three figural two-tone designs that were released solely in the United Kingdom. All three of the designs are scarce, each having been printed in a single print run according to Mrs. Robinson. The other two designs are Handlebar and Saddle. Curiously, Chain is the only one of the three that was issued with a black and brown back, instead of the usual blue and brown.

The back features a bicycle chain as a border motif. Another back design that uses a bicycle chain as a border element is Autocycle No. 1.

A brown and black Chain single sold on eBay on September 25, 2016 for $69. Of the two Chain versions, this is the hardest to find.
