Solitude was a French rock band active in the early 1970s. This single, released in 1973 on the Theleme label, comes with a typographic sleeve that features two typefaces available from Letraset. The song titles are in Desdemona Solid, a revival of a design that originated as Quaint at the Dickinson foundry in the 1880s, here used with inappropriate straight quotes. The band name is composed in Gary. The latter appears to be a Letraset original issued in 1970, when Art Nouveau was en vogue again.

The Theleme logo uses caps from Frankonia.

This single with two Elvis-themed disco tracks seems to be the only release by Kids of the King, a project by Eldo Papiri a.k.a. Aldo Frank (1941–2021). French label Disques Festival issued the 12″ record in 1978.

François Dupuich’s illustration obviously was made under the influence of Saturday Night Fever. The Art Nouveau letterforms are from a relatively rare typeface by Letraset, the manufacturer of dry transfer lettering: the all-caps Gary appears only in a few of their catalogs I’ve seen, with a 1970 date and no individual credits.
