Quite like these two personally:

What's your favourite manufacturers headtube badge or graphics?

My Cotic one made of (proper) silver.

I know, useless without pics. 😳

My IF badge is a little different, I've had 4 Orange sapphires mounted in the crown 😉

I do like my Spot Brand badge too.

Mind you, the Maverick one is cool too!

I think the Yo Eddy was also prety cool

Always looked good. I think the stars were a nod in the direction of the Brooklyn team or American market, not sure though?

Chromag

Oooo, I like that 🙂

This one is cool as. What is it? A sea-sheep?

nice classic there 🙂 does look like some sort of bizarre sea-sheep doesn't it! assuming it's a seahorse though?

I think it's a kelpie. Not that I'd want an evil water spirit on the front of a steel frame, but it takes all sorts.

As far as modern-day stuff goes I like the Singular badges, particularly the way you get a different one with each bike.

The top one appears to be suffering from conjunctivitis. 😉

i do like this

Ibis is a good one,

and, at the other end,

I still rather like the classic old bird, though;
