It's got the "Lave" which is always a good sign, and the "Lucy" looks like other exemplars I've seen. But I'm n expert - other opinions?
Was Lucy known to write Love like "Lave?"
I have an index card signed this way with "Lave" and I'm guessing, based on this and one other ttm I saw that it's ttm also.
Most of what I saw, pre 1980s ttms, were signed with a full "O" in Love, not looking like the "A" seen here.
