I'm looking for the font used on the Sgt. Pepper's Lonely Hearts Club Band album cover, specifically the part used for "LONELY HEARTS." I'm not sure if it's an actual typeface, but something similar would be appreciated.

Some letters are really different, but here's something somehow similar.

I thought for sure this was going to be erased... try Peignot - once the drop shadow and outline are added... the R was probably an alternative from typositor days... after all, this was the 60s - when typesetting ruled!

K-Type's 'Sgt Peppers Lonely Hearts Club' is a typeface inspired by the capital letters on the bass drum in the Beatles’ Sgt Pepper album cover. The original lettering was hand painted by fairground artist Joe Ephgrave during March 1967 in an art deco style he called ‘futuristic’. The font completes the uppercase, adds a lowercase, and includes a full complement of over 400 characters.

Two other fonts, Sgt Peppers Outline and Sgt Peppers Outline Fill, have matching spacing and kerning that can be overlapped for creating bicolor/multicolor effects and faux drums. The Outline and Outline Fill fonts do not contain lowercase characters, instead they comprise two weights of capitals as painted on the Sgt Pepper drum. The uppercase letters are in the wider style from around the outer edge of the drum, and the lowercase keys deliver the more condensed ‘Lonely Hearts’ inline style from the middle of the drum.

All three fonts are supplied when a licence is purchased, and the Outline version is available Free for Personal Use.
