Vintage U S Army recruiting posterboard—seeking info

[bamascvreb]

I acquired this recently and have searched for info on it but keep hitting dead ends. It was advertised as being from the 50s but the uniform is older i believe. It is a poster type material with a cardboard type backing although i believe it was produced this way instead of someone mounting it themselves. Im thinking it may have been used in a local recruiting office. The only writing i find on it are characters rpc-12-15-53-32m in the bottom right. I tried a while to get photos to work and this was best i could do. Any info would be appreciated.

Not sure on the time frame but the soldier appears to be working on a weather station.
