Valuation

[idiotian]

I have a couple of things I am trying to sell and am trying to get an idea of what they are worth.

The first is a signed Glen Fabry poster of Slaine - number 43 of 500, its the image where half the picture is his axe and a green splash!  it was signed 'Happy birthday Ian Love Glen Fabry' but most of this has faded, but his signature and 'happy' are fairly legible.

I also have a couple of what I think are litho plates for Judge Dredd strip titled 'Pirates of the Black Atlantic' part 4, and the plate for the cover of 2000AD prog 196 I got this signed on the back by Dave Gibbons in 2016, who was the cover artist. These are basically pale blue images on a white background.

Grateful for any ideas/suggestions
