Taking something on board a flight

[FlamingoFloss]

Hi All, I’m currently in Turkey and travelling home this evening. So I bought some artwork and the artist packaged it up for me - cue the problem, it doesn’t fit in my case! Even taking it out of the packaging it won’t fit!!!
DH seems to think we can take the tube as a carry on and it will be fine - I’m not so convinced!! We are flying easyJet. Anyone any experience? TIA
picture attached - it’s approx 1m tall and not heavy

I used to take a poster tube like that on easyJet for work as well as my hand luggage allowance and no one ever so much as raised an eyebrow at it.

Thanks for this!! We may try then ;)
