What guitar was at the johnny ramone tribute thing last night at hollywood forever cemetery?

last night i was at the johnny ramone tribute at hollywood forever cemetery (which was awesome) and in the deedee ramone art gallery they had a bunch of ramones stuff including one of johnny's guitars that said ramones model 1974 (i think) to 1990 something. It was blue and i was thinking it was johnny's blue mosrite, but it didn't really look like it. anybody know what guitar it was?
