This can also be done with sheet explosives. Some amazing results are
possible with this technique, like welding dissimilar metals. (Seen it on
Discovery)

While cleaning my parents garage, i found some artwork that i remember
seeing in their home in the 1950's.There are two etchings? of horses
on raised or embossed material which looks like thin aluminum or
bronze material and attached to wood with many small rivets. I was
just curious if anyone was familiar with this technique? It appears
that it is all done by hand as opposed to a template of some type.
