Don,
That's a GREAT matchbook Cover!

LV 1944 phone book shows:

*El Rancho Dio, Hwy 91, phone 1242-M
Prop Frank Dio Dato

*Frank Dio Dato, El Rancho Dio, Hwy 91, phone 1242

*No listing for Val Sneed

The 1945 phone book shows:

*El Rancho Dio, L A Hwy, phone #1242-M

*Val & Mable Sneed, r 1901 W. Bonanza, phone 146

*Frank Dio Dato, r L A Hwy, phone #1242-W
(I've always read that 'r' as 'residence')
(This is the first time I've noticed the same phone number listed with different letters)

A September 1945 business directory lists "Val Sneed's El Rancho Dio" under Gaming Casinos, phone 1242-M.

In the 1950 phone book, Frank Dio Dato is listed at 524 S. Fifth, phone 3722. No listings for Val Sneed or El Rancho Dio.

Sorry...couldn't find any listings for El Toro Bar.
