1973-74 O-Pee-Chee Hockey Forum

The first cards my dad ever bought me were the series 2 green cards.  He bought them several times, all were green.  I found out in the school yard that there were red cards.previously sold.  Can anyone tell me the months that the red cards were sold and then the months that the green cards were sold.  Thanks!

These were also the first cards I collected.. If I recall correctly it was in stores January of '74, in Toronto..

I am unaware of the release month for Series 1. 

Thanks!  I thought it might be January.  I seem to remember it being really cold and snowy.
