I came across these packets in one of the boxes that housed my father's collection (he gave it to me two weeks ago). A few other SCF threads discuss Harris but none address this
"Adventures with Postage Stamps" series which struck me as a great way to convey the linkage between the stamp and its historical background.
These twelve packets are still sealed but one duplicate was opened so I've included images of its content. Judging from the copyright date on the insert, H.E. Harris was distributing these in the mid- to late-1930s.




Sadly, Whitman Publishing's H.E. Harris line doesn't carry a modern day equivalent. Any thoughts on how to expose today's youth to philately through a Wii, Xbox or PlayStation?
