Steampunk Artifact Swap No 3

This is the third in the series! In this swap you will be sending your partner an article for their Cabinet of Curiousities! This be be a series swap that you can dip in and out of. The third swap will be a TRADE or OCCUPATION related artifact, then upcoming ones will be themed such as fossils, gems. skulls, machinery, historical etc (please PM me with more ideas).

Your third item must be related to a TRADE or OCCUPATION, but there are no other specifics. It could be a sign or poster, tool, item of stationary, anything required to perform a task or connected to a job. It could be a real thing, like a Victorian sewing kit or buttons from a uniform, or something fictional like an Airship pilots license or a secret agents calling card. Please be careful about sending natural material by post and double check that the item you are sending isn't banned by customs!

Please make such it is of a reasonable posting size (i.e. not a real airship or Singer sewing machine) and wrap carefully if it is delicate.

Have fun, and PM me with questions, suggestions and so on!
