Even in 1974 Energy Conservation
was a concern. Thought I'd share this great block of USPS commemorative stamps from Karen Horton's wonderful Flickr
The stamp was designed by Robert W. Bode and issued on 23 September 1974 to promote the importance of Energy Conservation and to coincide with the 9th World Energy Conference: 'The Economic and Environmental Challenges of Future Energy Requirements'
, held in Detroit, Michigan from 23-27 September.
I love the big, bold pink 'ENERGY' type (pink & orange are one of my favourite colour combos) - what's not to like!
Whilst doing some research I found a cool 70's poster
on Etsy that features this stamp.Image copyright Karen Horton. Via Vintage Postage Stamps.
