[78-L] RCA Victor reverse side "spider web" etching name?

[David Lennick]

These "web back" pressings go back to the early 1920s or even earlier (though 
not with "RCA" in those days) and into the fifties. RCA-pressed radio 
transcriptions also had them. I've also seen some LPs with a similar backing, 
on Angel sets that took an uneven number of sides. This was a bad idea because 
LP sets were often played on changers and these sides didn't have a clean 
groove running through them (unlike the 78s).
