Scotland is most famous for its "Shortbread" which is a cookie primarily made of flour, sugar, and butter. (Below are just a few of the many Scottish food tins for the TofT Museum.)

Campbells (Scottish Shortbread)
Exported tins to a U. S. company
Ian Logan (a London Company which produced tins)
Ian Logan was part of a textile design company beginning in the early 1960s & graduated onto "tin" in the 1970s. Then for 25 years beginning in the mid-1970s, he created "buildings" of various sizes and shapes illustrated by many designers. His interest began by reflecting life in the early 1800s and he gradually had commissions for the current-day, well-known stores throughout Britain, and some museums worldwide. The following is the only active website I've found with a story & some of his tins.
