From June 1974, here’s an odd ticket book. Gray Line Tours (link) was such a large tour company that they got their very own Disneyland ticket book!
The Main Gate admission ticket is missing, it appears to be the standard “green’ ticket, but I can’t tell for certain.
The tickets are all “E” tickets and a very different from any other tickets sold at the park. Neato drawings huh? My favorite is the Haunted Mansion on the upper left.
The attraction page has a slightly different font than the standard ticket book, I like it. Noteworthy; “America Sings Opens July 1974” and no more Pack Mules…
