"Mushroom Collecting for Beginners" print (1972)

There are at least four different covers on different editions of J. Walton Groves' Mushroom Collecting for Beginners, and this one's a bit of a puzzle—its cover says 1972, its inside says 1975. If it was first published in 1972, this cover has lapsed into public domain (reminder: Crown Copyright ends 50 years after a thing is first published). If it's the latter, don't buy this—it'd be infringement. Unfortunately, there isn't a Canadian Agricultural Pamphlet 24-Hour Hotline to answer this bit of trivia.

A booklet cover reproduction available at 12x18" or 24x36" on Epson Enhanced Matte 192 gsm paper printed with Epson UltraChrome XD2 archival ink. Sold in an open edition, unframed. The Canada Department of Agriculture wordmark on this cover has been replaced with the words ”Canadian Nature Bulletin” due to Section 9 of the Canadian Trademarks Act.
