Trading card photo of Ron Stewart as a member of the Toronto Maple Leafs. According to the seller, Ralston-Purina also printed trading cards on their pet food bags during the same 1963 to 1965 time period they were printing hockey trading cards on the backs of their Chex cereal boxes in the US and Canada. While the cereal box ones were on sturdier cardboard, the paper ones from the pet food bags had no such backing. Both styles of card were blank on the back, as the collector simply cut them from the box or bag.

"According to the VHC catalogue , these paper issued photos (as opposed to regular cardboard issue) were put out by the Ralston Purina company on bags of pet food and these were produced in very low numbers and are very tough to find in any condition."
