Medwick Granger Sign--Help Please

[tothrk]

In the current Clean Sweep auction (lot #684), there is a cardboard Granger Medwick sign. I've seen the repro made from tin. Were there any originals made from anything besides cardboard? I've been looking for one of these on and off for some time and this is the only original I have seen for auction. I just assumed originals would also be tin for some reason. Thanks.

The originals were made of heavy cardboard... i've never seem an original made of tin.

I used to have a group of Granger signs (no baseball) of sports stars of the day and they were all heavy cardboard.
