Reader's Digest issued several Elvis LPs. I am aware though of only two that were pressed/printed in Canada, but collector Barry McLean advises there are two more.
5-395-0 "Great Hits of 1956-57" (single LP)
RD4A "Elvis! His Greatest Hits" 7 LP box set
RD4A "Elvis Sings Inspirational Favorites" (single LP)
RBA-191 "The Legend Lives On" 7 LP box set
the brown label is unique to Canada
Sorry, images of the LP jackets are not yet available
