The first Del-Fi singles design had "Del-Fi" in 'gothic' styled letterings at the top of the label, with no other graphics (pics 196946/949 219496/498 411034/037). This one was issued in several colors, including yellow, gold, green, and blue for various singles.
It was replaced by fall, 1958, by the second design, shown on 410963 / 965 pics. This happened at least by #4106, (Come On, Let's Go" by Ritchie Valens) and was primaly colored in yellow, then in blue.
The sawtooth design label first appear in light blue and was used from may 1959 until the fall of 1961. Some Ritchie Valens singles were issued on a gold variation of this label
The black sawtooth design label (pics 279469/470) ran from 1962 until 1965.
Concerning #4110 :
- The contract-pressing was for the aqua/circles label ( pics 410963 / 965). But as pressing plants couldn't face the immediatly high demand, it was first issued with at least 3 different labels : aqua/contract label (No ®) and the older designed one in blue and in green colors.
Though the old stock was used at the same time as the aqua label, it is seems logical that the very first singles were issued with then current label. All three are nevertheless original pressings from the fall of 1958.
- 1959 issues were on the contract label but with the ® added on the right of the logo.
- The third design for this record : light blue label with black prints and sawtooth, and and a pale-grey label occasionaly (not shown here so far but i'll post an old scan of the grey variation) appeared on sept. 1959, (rarest issue)
- The lack label one (219469/470) was used for 1962 to 1965 issues.
- 'Valens Memorial Series' reissues also used that design but this time on dark gold label with black prints
